release output
--------------

   Before `release' releases your sources it will print a one-line
message for any file that is not up-to-date.

   *Warning:*  Any new directories that you have created, but not added
to the CVS directory hierarchy with the `add' command (*note add::.)
will be silently ignored (and deleted, if `-d' is specified), even if
they contain files.

`U FILE'
     There exists a newer revision of this file in the repository, and
     you have not modified your local copy of the file.

`A FILE'
     The file has been added to your private copy of the sources, but
     has not yet been committed to the repository.  If you delete your
     copy of the sources this file will be lost.

`R FILE'
     The file has been removed from your private copy of the sources,
     but has not yet been removed from the repository, since you have
     not yet committed the removal.  *Note commit::.

`M FILE'
     The file is modified in your working directory.  There might also
     be a newer revision inside the repository.

`? FILE'
     FILE is in your working directory, but does not correspond to
     anything in the source repository, and is not in the list of files
     for CVS to ignore (see the description of the `-I' option, and
     *note cvsignore::.).  If you remove your working sources, this
     file will be lost.

     Note that no warning message like this is printed for spurious
     directories that CVS encounters.  The directory, and all its
     contents, are silently ignored.


File: cvs.info,  Node: release examples,  Prev: release output,  Up: release

release examples
----------------

   Release the module, and delete your local working copy of the files.

     $ cd ..         # You must stand immediately above the
                     # sources when you issue `cvs release'.
     $ cvs release -d tc
     You have [0] altered files in this repository.

remove--Remove an entry from the repository
===========================================

   * remove [-lR] [files...]

   * Requires: Working directory.

   * Changes: Working directory.

   * Synonyms: rm, delete

   Use this command to declare that you wish to remove files from the
source repository.  Like most CVS commands, `cvs remove' works on files
in your working directory, not directly on the repository.  As a
safeguard, it also requires that you first erase the specified files
from your working directory.

   The files are not actually removed until you apply your changes to
the repository with `commit'; at that point, the corresponding RCS
files in the source repository are moved into the `Attic' directory
(also within the source repository).

   This command is recursive by default, scheduling all physically
removed files that it finds for removal by the next commit.  Use the
`-l' option to avoid this recursion, or just specify the actual files
that you wish removed.

* Menu:

* remove examples::             remove examples


File: cvs.info,  Node: remove options,  Next: remove examples,  Up: remove

remove options
--------------

   Two of the standard options are the only options supported by
`remove'.

`-l'
     Local; run only in current working directory.

`-R'
     Commit directories recursively.  This is on by default.

remove examples
---------------

Remove a couple of files.
.........................

     $ cd test
     $ rm ?.c
     $ cvs remove
     cvs remove: Removing .
     cvs remove: scheduling a.c for removal
     cvs remove: scheduling b.c for removal
     cvs remove: use 'cvs commit' to remove these files permanently
     $ cvs ci -m "Removed unneeded files"
     cvs commit: Examining .
     cvs commit: Committing .

Resurrecting removed files
..........................

   If you change your mind you can easily resurrect the file before you
commit it, using the `add' command.

     $ ls
     CVS   ja.h  oj.c
     $ rm oj.c
     $ cvs remove oj.c
     cvs remove: scheduling oj.c for removal
     cvs remove: use 'cvs commit' to remove this file permanently
     $ cvs add oj.c
     U oj.c
     cvs add: oj.c, version 1.1.1.1, resurrected

   If you realize your mistake before you run the `remove' command you
can use `update' to resurrect the file:

     $ rm oj.c
     $ cvs update oj.c
     cvs update: warning: oj.c was lost
     U oj.c


File: cvs.info,  Node: rtag,  Next: status,  Prev: remove,  Up: Invoking CVS

rtag--Add a tag to the RCS file
===============================

   * rtag [-falnRQq] [-b] [-d] [-r tag | -Ddate] symbolic_tag modules...

   * Requires: repository.

   * Changes: repository.

   * Synonym: rfreeze

   You can use this command to assign symbolic tags to particular,
explicitly specified source revisions in the repository.  `rtag' works
directly on the repository contents (and requires no prior checkout).
Use `tag' instead (*note tag::.), to base the selection of revisions on
the contents of your working directory.

   If you attempt to use a tag name that already exists, CVS will
complain and not overwrite that tag.  Use the `-F' option to force the
new tag value.

* Menu:

* rtag options::                rtag options


File: cvs.info,  Node: rtag options,  Up: rtag

rtag options
------------

   These standard options are supported by `rtag' (*note Common
options::., for a complete description of them):

`-D DATE'
     Tag the most recent revision no later than DATE.

`-f'
     Only useful with the `-D DATE' or `-r TAG' flags.  If no matching
     revision is found, use the most recent revision (instead of
     ignoring the file).

`-F'
     Overwrite an existing tag of the same name on a different
     revision.  This option is new in CVS 1.4.  The old behavior is
     matched by `cvs tag -F'.

`-l'
     Local; run only in current working directory.

`-n'
     Do not run any tag program that was specified with the `-t' flag
     inside the `modules' file.  (*note modules::.).

`-R'
     Commit directories recursively.  This is on by default.

`-r TAG'
     Only tag those files that contain TAG.  This can be used to rename
     a tag: tag only the files identified by the old tag, then delete
     the old tag, leaving the new tag on exactly the same files as the
     old tag.

   In addition to the above common options, these options are available:

`-a'
     Use the `-a' option to have `rtag' look in the `Attic' (*note
     Removing files::.) for removed files that contain the specified
     tag.  The tag is removed from these files, which makes it
     convenient to re-use a symbolic tag as development continues (and
     files get removed from the up-coming distribution).

`-b'
     Make the tag a branch tag.  *Note Branches::.

`-d'
     Delete the tag instead of creating it.

     In general, tags (often the symbolic names of software
     distributions) should not be removed, but the `-d' option is
     available as a means to remove completely obsolete symbolic names
     if necessary (as might be the case for an Alpha release, or if you
     mistagged a module).


File: cvs.info,  Node: status,  Next: tag,  Prev: rtag,  Up: Invoking CVS

status--Status info on the revisions
====================================

   * status [-lR] [-v] [files...]

   * Requires: working directory, repository.

   * Changes: nothing.

   Display a brief report on the current status of files with respect
to the source repository, including any sticky tags, dates, or `-k'
options.

   You can also use this command to determine the potential impact of a
`cvs update' on your working source directory--but remember that things
might change in the repository before you run `update'.

* Menu:

* status options::              status options


File: cvs.info,  Node: status options,  Up: status

status options
--------------

   These standard options are supported by `status' (*note Common
options::., for a complete description of them):

`-l'
     Local; run only in current working directory.

`-R'
     Commit directories recursively.  This is on by default.

   There is one additional option:

`-v'
     Verbose.  In addition to the information normally displayed, print
     all symbolic tags, together with the numerical value of the
     revision or branch they refer to.


File: cvs.info,  Node: tag,  Next: update,  Prev: status,  Up: Invoking CVS

tag--Add a symbolic tag to checked out version of RCS file
==========================================================

   * tag [-lQqR] [-b] [-d] symbolic_tag [files...]

   * Requires: working directory, repository.

   * Changes: repository.

   * Synonym: freeze

   Use this command to assign symbolic tags to the nearest repository
versions to your working sources.  The tags are applied immediately to
the repository, as with `rtag', but the versions are supplied
implicitly by the CVS records of your working files' history rather than
applied explicitly.

   One use for tags is to record a snapshot of the current sources when
the software freeze date of a project arrives.  As bugs are fixed after
the freeze date, only those changed sources that are to be part of the
release need be re-tagged.

   The symbolic tags are meant to permanently record which revisions of
which files were used in creating a software distribution.  The
`checkout' and `update' commands allow you to extract an exact copy of
a tagged release at any time in the future, regardless of whether files
have been changed, added, or removed since the release was tagged.

   This command can also be used to delete a symbolic tag, or to create
a branch.  See the options section below.

   If you attempt to use a tag name that already exists, CVS will
complain and not overwrite that tag.  Use the `-F' option to force the
new tag value.

* Menu:

* tag options::                 tag options


File: cvs.info,  Node: tag options,  Up: tag

tag options
-----------

   These standard options are supported by `tag' (*note Common
options::., for a complete description of them):

`-F'
     Overwrite an existing tag of the same name on a different
     revision.  This option is new in CVS 1.4.  The old behavior is
     matched by `cvs tag -F'.

`-l'
     Local; run only in current working directory.

`-R'
     Commit directories recursively.  This is on by default.

   Two special options are available:

`-b'
     The -b option makes the tag a branch tag (*note Branches::.),
     allowing concurrent, isolated development.  This is most useful
     for creating a patch to a previously released software
     distribution.

`-d'
     Delete a tag.

     If you use `cvs tag -d symbolic_tag', the symbolic tag you specify
     is deleted instead of being added.  Warning: Be very certain of
     your ground before you delete a tag; doing this permanently
     discards some historical information, which may later turn out to
     be valuable.

update--Bring work tree in sync with repository
===============================================

   * update [-AdflPpQqR] [-d] [-r tag|-D date] files...

   * Requires: repository, working directory.

   * Changes: working directory.

   After you've run checkout to create your private copy of source from
the common repository, other developers will continue changing the
central source.  From time to time, when it is convenient in your
development process, you can use the `update' command from within your
working directory to reconcile your work with any revisions applied to
the source repository since your last checkout or update.

* Menu:

* update options::              update options
* update output::               update output
* update examples::             update examples


File: cvs.info,  Node: update options,  Next: update output,  Up: update

update options
--------------

   These standard options are available with `update' (*note Common
options::., for a complete description of them):

`-D date'
     Use the most recent revision no later than DATE.  This option is
     sticky, and implies `-P'.

`-f'
     Only useful with the `-D DATE' or `-r TAG' flags.  If no matching
     revision is found, retrieve the most recent revision (instead of
     ignoring the file).

`-k KFLAG'
     Process RCS keywords according to KFLAG.  See co(1).  This option
     is sticky; future updates of this file in this working directory
     will use the same KFLAG.  The `status' command can be viewed to
     see the sticky options.  *Note status::.

`-l'
     Local; run only in current working directory.

`-P'
     Prune empty directories.

`-p'
     Pipe files to the standard output.

`-R'
     Commit directories recursively.  This is on by default.

`-r tag'
     Retrieve revision TAG.  This option is sticky, and implies `-P'.

   These special options are also available with `update'.

`-A'
     Reset any sticky tags, dates, or `-k' options.  (If you get a
     working copy of a file by using one of the `-r', `-D', or `-k'
     options, CVS remembers the corresponding tag, date, or KFLAG and
     continues using it on future updates; use the `-A' option to make
     CVS forget these specifications, and retrieve the head revision of
     the file).

`-d'
     Create any directories that exist in the repository if they're
     missing from the working directory.  Normally, `update' acts only
     on directories and files that were already enrolled in your
     working directory.

     This is useful for updating directories that were created in the
     repository since the initial checkout; but it has an unfortunate
     side effect.  If you deliberately avoided certain directories in
     the repository when you created your working directory (either
     through use of a module name or by listing explicitly the files
     and directories you wanted on the command line), then updating
     with `-d' will create those directories, which may not be what you
     want.

`-I NAME'
     Ignore files whose names match NAME (in your working directory)
     during the update.  You can specify `-I' more than once on the
     command line to specify several files to ignore.  By default,
     `update' ignores files whose names match any of the following:

                  RCSLOG  RCS     SCCS
                  CVS*    cvslog.*
                  tags    TAGS
                  .make.state     .nse_depinfo
                  *~      #*      .#*     ,*
                  *.old   *.bak   *.BAK   *.orig  *.rej   .del-*
                  *.a     *.o     *.so    *.Z     *.elc   *.ln
                  core

     Use `-I !' to avoid ignoring any files at all.  *Note cvsignore::,
     for other ways to make CVS ignore some files.

`-WSPEC'
     Specify file names that should be filtered during update.  You can
     use this option repeatedly.

     SPEC can be a file name pattern of the same type that you can
     specify in the `.cvswrappers' file. *Note Wrappers::.

`-jBRANCH'
     Merge the changes made between the resulting revision and the
     revision that it is based on (e.g., if the tag refers to a branch,
     CVS will merge all changes made in that branch into your working
     file).

     With two `-j' options, CVS will merge in the changes between the
     two respective revisions.  This can be used to remove a certain
     delta from your working file;  if the file `foo.c' is based on
     revision 1.6 and you want to remove the changes made between 1.3
     and 1.5, you might do:

          $ cvs update -j1.5 -j1.3 foo.c   # note the order...

     In addition, each -j option can contain an optional date
     specification which, when used with branches, can limit the chosen
     revision to one within a specific date.  An optional date is
     specified by adding a colon (:) to the tag:
     `-jSYMBOLIC_TAG:DATE_SPECIFIER'.


File: cvs.info,  Node: update output,  Next: update examples,  Prev: update options,  Up: update

update output
-------------

   `update' keeps you informed of its progress by printing a line for
each file, preceded by one character indicating the status of the file:

`U FILE'
     The file was brought up to date with respect to the repository.
     This is done for any file that exists in the repository but not in
     your source, and for files that you haven't changed but are not
     the most recent versions available in the repository.

`A FILE'
     The file has been added to your private copy of the sources, and
     will be added to the source repository when you run `commit' on
     the file.  This is a reminder to you that the file needs to be
     committed.

`R FILE'
     The file has been removed from your private copy of the sources,
     and will be removed from the source repository when you run
     `commit' on the file.  This is a reminder to you that the file
     needs to be committed.

`M FILE'
     The file is modified in  your  working  directory.

     `M' can indicate one of two states for a file you're working on:
     either there were no modifications to the same file in the
     repository, so that your file remains as you last saw it; or there
     were modifications in the repository as well as in your copy, but
     they were merged successfully, without conflict, in your working
     directory.

     CVS will print some messages if it merges your work, and a backup
     copy of your working file (as it looked before you ran `update')
     will be made.  The exact name of that file is printed while
     `update' runs.

`C FILE'
     A conflict was detected while trying to merge your changes to FILE
     with changes from the source repository.  FILE (the copy in your
     working directory) is now the output of the rcsmerge(1) command on
     the two revisions; an unmodified copy of your file is also in your
     working directory, with the name `.#FILE.REVISION' where REVISION
     is the RCS revision that your modified file started from.  (Note
     that some systems automatically purge files that begin with `.#'
     if they have not been accessed for a few days.  If you intend to
     keep a copy of your original file, it is a very good idea to rename
     it.)

`? FILE'
     FILE is in your working directory, but does not correspond to
     anything in the source repository, and is not in the list of files
     for CVS to ignore (see the description of the `-I' option, and
     *note cvsignore::.).

     Note that no warning message like this is printed for spurious
     directories that CVS encounters.  The directory, and all its
     contents, are silently ignored.

   Inside the repository, in the directory `$CVSROOT/CVSROOT', there
are a number of supportive files for CVS.  You can use CVS in a limited
fashion without any of them, but if they are set up properly they can
help make life easier.

   The most important of these files is the `modules' file, which
defines the modules inside the repository.

File: cvs.info,  Node: modules,  Next: Wrappers,  Up: Administrative files

The modules file
================

   The `modules' file records your definitions of names for collections
of source code.  CVS will use these definitions if you create a file
with the right format in `$CVSROOT/CVSROOT/modules,v'.  The
mkmodules(1) command should be run whenever the modules file changes,
so that the appropriate files can be generated (depending on how you
have configured CVS operation).

   To allow convenient editing of the `modules' file itself, the file
should include an entry like the following (where LOCALBIN represents
the directory where your site installs programs like mkmodules(1)):

     modules    -i /LOCALBIN/mkmodules CVSROOT modules

This defines the name `modules' as the module name for the file itself,
so that you can use

     $ cvs checkout modules

to get a copy of the file that you can edit.  You should define similar
module entries for the other configuration files described in this
appendix, except `history').

   The `modules' file may contain blank lines and comments (lines
beginning with `#') as well as module definitions.  Long lines can be
continued on the next line by specifying a backslash (`\') as the last
character on the line.

   A module definition is a single line of the `modules' file, in
either of two formats.  In both cases, MNAME represents the symbolic
module name, and the remainder of the line is its definition.

`MNAME -a ALIASES...'
     This represents the simplest way of defining a module MNAME.  The
     `-a' flags the definition as a simple alias: CVS will treat any
     use of MNAME (as a command argument) as if the list of names
     ALIASES had been specified instead.  ALIASES may contain either
     other module names or paths.  When you use paths in aliases,
     `checkout' creates all intermediate directories in the working
     directory, just as if the path had been specified explicitly in
     the CVS arguments.

`MNAME [ options ] DIR [ FILES... ] [ &MODULE... ]'
     In the simplest case, this form of module definition reduces to
     `MNAME DIR'.  This defines all the files in directory DIR as
     module mname.  DIR is a relative path (from `$CVSROOT') to a
     directory of source in the source repository.  In this case, on
     checkout, a single directory called MNAME is created as a working
     directory; no intermediate directory levels are used by default,
     even if DIR was a path involving several directory levels.

     By explicitly specifying files in the module definition after DIR,
     you can select particular files from directory DIR.  The sample
     definition for `modules' is an example of a module defined with a
     single file from a particular directory.  Here is another example:

          m4test  unsupported/gnu/m4 foreach.m4 forloop.m4

     With this definition, executing `cvs checkout m4test' will create
     a single working directory `m4test' containing the two files
     listed, which both come from a common directory several levels deep
     in the CVS source repository.

     A module definition can refer to other modules by including
     `&MODULE' in its definition.  `checkout' creates a subdirectory
     for each such module, in your working directory.

    `-d NAME'
          Name the working directory something other than the module
          name.

    `-i PROG'
          Specify a program PROG to run whenever files in a module are
          committed.  PROG runs with a single argument, the full
          pathname of the affected directory in a source repository.
          The `commitinfo', `loginfo', and `editinfo' files provide
          other ways to call a program on commit.

    `-o PROG'
          Specify a program PROG to run whenever files in a module are
          checked out.  PROG runs with a single argument, the module
          name.

    `-s STATUS'
          Assign a status to the module.  When the module file is
          printed with `cvs checkout -s' the modules are sorted
          according to primarily module status, and secondarily
          according to the module name.  This option has no other
          meaning.  You can use this option for several things besides
          status: for instance, list the person that is responsible for
          this module.

    `-t PROG'
          Specify a program PROG to run whenever files in a module are
          tagged with `rtag'.  PROG runs with two arguments: the module
          name and the symbolic tag specified to `rtag'.  There is no
          way to specify a program to run when `tag' is executed.

    `-u PROG'
          Specify a program PROG to run whenever `cvs update' is
          executed from the top-level directory of the checked-out
          module.  PROG runs with a single argument, the full path to
          the source repository for this module.

The cvswrappers file
====================

   Wrappers are essentially directories that are to be treated as
"files."  This package allows such wrappers to be "processed" on the
way in and out of CVS.  The intended use is to wrap up a wrapper into a
single tar, such that that tar can be treated as a single binary file
in CVS.  Apparently this is particularly useful on NEXTSTEP.  To solve
the problem effectively, it was also necessary to be able to prevent
rcsmerge application at appropriate times.

   The file `cvswrappers' defines the script that will be run on a file
when its name matches a regular expresion. There are two scripts that
can be run on a file or directory.  A script to filter the
directory/file before it gets checked in and another that is run when
the file/directory gets checked out.

   The `cvswrappers' also specifies the merge methodology that should
be used when the file is updated, that is should a MERGE or a straight
COPY of the diferences be used when checking into the repository.

   The basic format of the file `cvswrappers' is given as such:

     wildcard     [option value][option value]...
     
     where option is one of
     -f           from cvs filter         value: path tofilter
     -t           to cvs filter           value: path to filter
     -m           update methodology      value: MERGE or COPY
     
     and value is a single-quote delimited value.

     *.nib    -f 'uncom %s' -t 'comb %s %s' -m 'COPY'
     *.rtfd   -f 'uncom %s' -t 'comb %s %s' -m 'COPY'

The above example of a `cvswrappers' file states that all
files/directories that end with a `.nib' should be filtered with the
`comb' program before checking the file into the repository. The file
should be filtered though the `uncom' program when the file is checked
out of the repository. The `cvswrappers' file also states that a `COPY'
methodology should be used when updating the files in the repository
(that is no merging should be performed).

The `comb' filter is called with two arguments, the first is the name
of the file/directory to filter and the second is the pathname to where
the resulting filtered file should be placed.

The `uncom' filter is called with one argument, which is the name of
the file to filter from. The end result of the `uncom' filter will be a
file/directory in the users current working directory, that represents
the source before being filtered.

The commit support files
========================

   The `-i' flag in the `modules' file can be used to run a certain
program whenever files are committed (*note modules::.).  The files
described in this section provide other, more flexible, ways to run
programs whenever something is committed.

   There are three kind of programs that can be run on commit.  They
are specified in files in the repository, as described below.  The
following table summarizes the file names and the purpose of the
corresponding programs.

`commitinfo'
     The program is responsible for checking that the commit is
     allowed.  If it exits with a non-zero exit status the commit will
     be aborted.

`editinfo'
     The specified program is used to edit the log message, and
     possibly verify that it contains all required fields.  This is
     most useful in combination with the `rcsinfo' file, which can hold
     a log message template (*note rcsinfo::.).

`loginfo'
     The specified program is called when the commit is complete.  It
     receives the log message and some additional information and can
     store the log message in a file, or mail it to appropriate
     persons, or maybe post it to a local newsgroup, or...  Your
     imagination is the limit!

The common syntax
-----------------

   The four files `commitinfo', `loginfo', `rcsinfo' and `editinfo' all
have a common format.  The purpose of the files are described later on.
The common syntax is described here.

   Each line contains the following:
   * A regular expression

   * A whitespace separator--one or more spaces and/or tabs.

   * A file name or command-line template.

Blank lines are ignored.  Lines that start with the character `#' are
treated as comments.  Long lines unfortunately can *not* be broken in
two parts in any way.

   The first regular expression that matches the current directory name
in the repository is used.  The rest of the line is used as a file name
or command-line as appropriate.


File: cvs.info,  Node: commitinfo,  Next: editinfo,  Prev: commit files,  Up: Administrative files

Commitinfo
==========

   The `commitinfo' file defines programs to execute whenever `cvs
commit' is about to execute.  These programs are used for pre-commit
checking to verify that the modified, added and removed files are really
ready to be committed.  This could be used, for instance, to verify
that the changed files conform to to your site's standards for coding
practice.

   As mentioned earlier, each line in the `commitinfo' file consists of
a regular expression and a command-line template.  The template can
include a program name and any number of arguments you wish to supply
to it.  The full path to the current source repository is appended to
the template, followed by the file names of any files involved in the
commit (added, removed, and modified files).

   The first line with a regular expression matching the relative path
to the module will be used.  If the command returns a non-zero exit
status the commit will be aborted.

   If the repository name does not match any of the regular expressions
in this file, the `DEFAULT' line is used, if it is specified.

   All occurances of the name `ALL' appearing as a regular expression
are used in addition to the first matching regular expression or the
name `DEFAULT'.

   Note: when CVS is accessing a remote repository, `commitinfo' will
be run on the *remote* (i.e., server) side, not the client side (*note
Remote repositories::.).


File: cvs.info,  Node: editinfo,  Next: loginfo,  Prev: commitinfo,  Up: Administrative files

Editinfo
========

   If you want to make sure that all log messages look the same way,
you can use the `editinfo' file to specify a program that is used to
edit the log message.  This program could be a custom-made editor that
always enforces a certain style of the log message, or maybe a simple
shell script that calls an editor, and checks that the entered message
contains the required fields.

   If no matching line is found in the `editinfo' file, the editor
specified in the environment variable `$CVSEDITOR' is used instead.  If
that variable is not set, then the environment variable `$EDITOR' is
used instead.  If that variable is not set a precompiled default,
normally `vi', will be used.

   The `editinfo' file is often most useful together with the `rcsinfo'
file, which can be used to specify a log message template.

   Each line in the `editinfo' file consists of a regular expression
and a command-line template.  The template must include a program name,
and can include any number of arguments.  The full path to the current
log message template file is appended to the template.

   One thing that should be noted is that the `ALL' keyword is not
supported.  If more than one matching line is found, the first one is
used.  This can be useful for specifying a default edit script in a
module, and then overriding it in a subdirectory.

   If the repository name does not match any of the regular expressions
in this file, the `DEFAULT' line is used, if it is specified.

   If the edit script exits with a non-zero exit status, the commit is
aborted.

   Note: when CVS is accessing a remote repository, `editinfo' will be
run on the *remote* (i.e., server) side, not the client side (*note
Remote repositories::.).

Editinfo example
----------------

   The following is a little silly example of a `editinfo' file,
together with the corresponding `rcsinfo' file, the log message
template and an editor script.  We begin with the log message template.
We want to always record a bug-id number on the first line of the log
message.  The rest of log message is free text.  The following template
is found in the file `/usr/cvssupport/tc.template'.

     BugId:

   The script `/usr/cvssupport/bugid.edit' is used to edit the log
message.

     #!/bin/sh
     #
     #       bugid.edit filename
     #
     #  Call $EDITOR on FILENAME, and verify that the
     #  resulting file contains a valid bugid on the first
     #  line.
     if [ "x$EDITOR" = "x" ]; then EDITOR=vi; fi
     if [ "x$CVSEDITOR" = "x" ]; then CVSEDITOR=$EDITOR; fi
     $CVSEDITOR $1
     until head -1|grep '^BugId:[ ]*[0-9][0-9]*$' < $1
     do  echo -n  "No BugId found.  Edit again? ([y]/n)"
         read ans
         case ${ans} in
             n*) exit 1;;
         esac
         $CVSEDITOR $1
     done

   The `editinfo' file contains this line:

     ^tc     /usr/cvssupport/bugid.edit

   The `rcsinfo' file contains this line:

     ^tc     /usr/cvssupport/tc.template


File: cvs.info,  Node: loginfo,  Next: rcsinfo,  Prev: editinfo,  Up: Administrative files

Loginfo
=======

   The `loginfo' file is used to control where `cvs commit' log
information is sent.  The first entry on a line is a regular expression
which is tested against the directory that the change is being made to,
relative to the `$CVSROOT'.  If a match is found, then the remainder of
the line is a filter program that should expect log information on its
standard input.

   The filter program may use one and only one % modifier (a la
printf).  If `%s' is specified in the filter program, a brief title is
included (enclosed in single quotes) showing the modified file names.

   If the repository name does not match any of the regular expressions
in this file, the `DEFAULT' line is used, if it is specified.

   All occurances of the name `ALL' appearing as a regular expression
are used in addition to the first matching regular expression or
`DEFAULT'.

   The first matching regular expression is used.

   *Note commit files::, for a description of the syntax of the
`loginfo' file.

   Note: when CVS is accessing a remote repository, `loginfo' will be
run on the *remote* (i.e., server) side, not the client side (*note
Remote repositories::.).

* Menu:

* loginfo example::             Loginfo example


File: cvs.info,  Node: loginfo example,  Up: loginfo

Loginfo example
---------------

   The following `loginfo' file, together with the tiny shell-script
below, appends all log messages to the file
`$CVSROOT/CVSROOT/commitlog', and any commits to the administrative
files (inside the `CVSROOT' directory) are also logged in
`/usr/adm/cvsroot-log' and mailed to ceder.

     ALL             /usr/local/bin/cvs-log $CVSROOT/CVSROOT/commitlog
     ^CVSROOT        Mail -s %s ceder
     ^CVSROOT        /usr/local/bin/cvs-log /usr/adm/cvsroot-log

   The shell-script `/usr/local/bin/cvs-log' looks like this:

     #!/bin/sh
     (echo "-----------------------------------------------------------------";
      echo -n $USER"  ";
      date;
      echo;
      sed '1s+'${CVSROOT}'++') >> $1


File: cvs.info,  Node: rcsinfo,  Next: cvsignore,  Prev: loginfo,  Up: Administrative files

Rcsinfo
=======

   The `rcsinfo' file can be used to specify a form to edit when
filling out the commit log.  The `rcsinfo' file has a syntax similar to
the `editinfo', `commitinfo' and `loginfo' files.  *Note syntax::.
Unlike the other files the second part is *not* a command-line
template.  Instead, the part after the regular expression should be a
full pathname to a file containing the log message template.

   If the repository name does not match any of the regular expressions
in this file, the `DEFAULT' line is used, if it is specified.

   All occurances of the name `ALL' appearing as a regular expression
are used in addition to the first matching regular expression or
`DEFAULT'.

   The log message template will be used as a default log message.  If
you specify a log message with `cvs commit -m MESSAGE' or `cvs commit -f
FILE' that log message will override the template.

   *Note editinfo example::, for an example `rcsinfo' file.

   Note: when CVS is accessing a remote repository, `rcsinfo' will be
run on the *remote* (i.e., server) side, not the client side (*note
Remote repositories::.).

Ignoring files via cvsignore
============================

   There are certain file names that frequently occur inside your
working copy, but that you don't want to put under CVS control.
Examples are all the object files that you get while you compile your
sources.  Normally, when you run `cvs update', it prints a line for
each file it encounters that it doesn't know about (*note update
output::.).

   CVS has a list of files (or sh(1) file name patterns) that it should
ignore while running `update', `import' and `release'.  This list is
constructed in the following way.

   * The list is initialized to the following file name patterns:

              RCSLOG  RCS     SCCS
              CVS*    cvslog.*
              tags    TAGS
              .make.state     .nse_depinfo
              *~      #*      .#*     ,*
              *.old   *.bak   *.BAK   *.orig  *.rej   .del-*
              *.a     *.o     *.so    *.Z     *.elc   *.ln
              core

   * The per-repository list in `$CVSROOT/CVSROOT/cvsignore' is
     appended to the list, if that file exists.

   * The per-user list in `.cvsignore' in your home directory is
     appended to the list, if it exists.

   * Any entries in the environment variable `$CVSIGNORE' is appended
     to the list.

   * Any `-I' options given to CVS is appended.

   * As CVS traverses through your directories, the contents of any
     `.cvsignore' will be appended to the list.  The patterns found in
     `.cvsignore' are only valid for the directory that contains them,
     not for any sub-directories.

   In any of the 5 places listed above, a single exclamation mark (`!')
clears the ignore list.  This can be used if you want to store any file
which normally is ignored by CVS.

The history file
================

   The file `$CVSROOT/CVSROOT/history' is used to log information for
the `history' command (*note history::.).  This file must be created to
turn on logging.  This is done automatically if the `cvsinit' script is
used to set up the repository.

   The file format of the `history' file is unfortunately not yet
documented anywhere, but it is fairly easy to understand most of it.


File: cvs.info,  Node: Setting up,  Prev: history file,  Up: Administrative files

Setting up the repository
=========================

   When you install CVS for the first time, you should follow the
instructions in the `INSTALL' file to set up the repository.

   If you want to set up another repository, the easiest way to get a
reasonable set of working administrative files is to run the `cvsinit'
shell script.  It will set up an empty repository in the directory
defined by the environment variable `$CVSROOT'.  (`cvsinit' is careful
to never overwrite any existing files in the repository, so no harm is
done if you run `cvsinit' on an already set-up repository.  In fact,
running it on an already set-up repository is the best way to update
the various scripts from the `contrib' directory.)


File: cvs.info,  Node: Environment variables,  Next: Troubleshooting,  Prev: Administrative files,  Up: Top

All environment variables which affect CVS
******************************************

   This is a complete list of all environment variables that affect CVS.

`$CVSIGNORE'
     A whitespace-separated list of file name patterns that CVS should
     ignore. *Note cvsignore::.

`$CVSWRAPPERS'
     A whitespace-separated list of file name patterns that CVS should
     treat as wrappers. *Note Wrappers::.

`$CVSREAD'
     If this is set, `checkout' and `update' will try hard to make the
     files in your working directory read-only.  When this is not set,
     the default behavior is to permit modification of your working
     files.

`$CVSROOT'
     Should contain the full pathname to the root of the CVS source
     repository (where the RCS history files are kept).  This
     information must be available to CVS for most commands to execute;
     if `$CVSROOT' is not set, or if you wish to override it for one
     invocation, you can supply it on the command line: `cvs -d cvsroot
     cvs_command...' You may not need to set `$CVSROOT' if your CVS
     binary has the right path compiled in.

`$EDITOR'
`$CVSEDITOR'
     Specifies the program to use for recording log messages during
     commit.  If not set, the default is `/usr/ucb/vi'.  `$CVSEDITOR'
     overrides `$EDITOR'.  `$CVSEDITOR' does not exist in CVS 1.3, but
     the next release will probably include it.

`$PATH'
     If `$RCSBIN' is not set, and no path is compiled into CVS, it will
     use `$PATH' to try to find all programs it uses.

`$RCSBIN'
     Specifies the full pathname of the location of RCS programs, such
     as co(1) and ci(1).  If not set, a compiled-in value is used, or
     your `$PATH' is searched.

   CVS is a front-end to RCS.  The following environment variables
affect RCS:

`$LOGNAME'
`$USER'
     If set, they affect who RCS thinks you are.  If you have trouble
     checking in files it might be because your login name differs from
     the setting of e.g.  `$LOGNAME'.

`$RCSINIT'
     Options prepended to the argument list, separated by spaces.  A
     backslash escapes spaces within an option.  The `$RCSINIT' options
     are prepended to the argument lists of most RCS commands.

`$TMPDIR'
`$TMP'
`$TEMP'
     Name of the temporary directory.  The environment variables are
     inspected in the order they appear above and the first value found
     is taken; if none of them are set, a host-dependent default is
     used, typically `/tmp'.

* Magic branch numbers::        Magic branch numbers


File: cvs.info,  Node: Magic branch numbers,  Up: Troubleshooting

Magic branch numbers
====================

   Externally, branch numbers consist of an odd number of dot-separated
decimal integers.  *Note Revision numbers::.  That is not the whole
truth, however.  For efficiency reasons CVS sometimes inserts an extra 0
in the second rightmost position (1.2.3 becomes 1.2.0.3, 8.9.10.11.12
becomes 8.9.10.11.0.12 and so on).

   CVS does a pretty good job at hiding these so called magic branches,
but in at least four places the hiding is incomplete.

   * The magic branch can appear in the output from `cvs status' in
     vanilla CVS 1.3.  This is fixed in CVS 1.3-s2.

   * The magic branch number appears in the output from `cvs log'.
     This is much harder to fix, since `cvs log' runs `rlog' (which is
     part of the RCS distribution), and modifying `rlog' to know about
     magic branches would probably break someone's habits (if they use
     branch 0 for their own purposes).

   * You cannot specify a symbolic branch name to `cvs log'.

   * You cannot specify a symbolic branch name to `cvs admin'.

   You can use the `admin' command to reassign a symbolic name to a
branch the way RCS expects it to be.  If `R4patches' is assigned to the
branch 1.4.2 (magic branch number 1.4.0.2) in file `numbers.c' you can
do this:

     $ cvs admin -NR4patches:1.4.2 numbers.c

   It only works if at least one revision is already committed on the
branch.  Be very careful so that you do not assign the tag to the wrong
number.  (There is no way to see how the tag was assigned yesterday).
