+=head1 NAME
+
+README.pod - README for the F<Porting/> directory in the Perl 5 core distribution.
+
+=head1 FILES
+
+=head2 F<acknowledgements.pl>
+
+Generates the text which goes in the Acknowledgements section in
+a perldelta. You pass in the previous version and it guesses the next
+version, fetches information from the repository and outputs the
+text.
+
+=head2 F<add-package.pl>
+
+Program to prepare dual-life distributions for insertion into the Perl 5
+F<lib/> and F<t/> directories.  Now thought to be largely superseded.
+
+=head2 F<bisect-example.sh>, F<bisect-runner.pl> and F<bisect.pl>
+
+Use C<git bisect> to pinpoint changes.
+
+=head2 F<bump-perl-version>
+
+A utility to find, and optionally bump, references to the perl version
+number in various files within the perl source.
+
+=head2 F<check83.pl>
+
+Performs pathname portability checks, including whether there are naming
+conflicts when names are truncated to the DOSish, case-ignoring 8.3 format.
+
+=head2 F<checkAUTHORS.pl>
+
+Used by F<t/porting/authors.t> to ensure the F<AUTHORS> list is up to date.
+
+=head2 F<checkURL.pl>
+
+Checks that all the URLs in the Perl source are valid.
+
+=head2 F<checkVERSION.pl>
+
+Used by F<t/porting/cmp_version.t> to ensure changed modules have had their
+versions updated.
+
+=head2 F<checkansi.pl>
+
+Check source code for ANSI-C violations.
+
+=head2 F<checkcfgvar.pl>
+
+Check that the various F<config.sh>-clones have (at least) all the same
+symbols as the top-level F<config_h.SH> so that the (potentially) needed
+symbols are not lagging after how F<Configure> thinks the world is laid out.
+VMS is probably not handled properly here, due to their own rather elaborate
+DCL scripting.
+
+=head2 F<check-cpan-pollution>
+
+Scans the commit logs for commits that are potentially, illegitimately
+touching modules that are primarily maintained outside of the perl core.  Also
+checks for commits that span multiple distributions in F<cpan/> or F<dist/>.
+Makes sure that updated CPAN distributions also update
+F<Porting/Maintainers.pl>, but otherwise ignores changes to that file (and
+F<MANIFEST>).
+
+=head2 F<checkpodencoding.pl>
+
+Check if POD files contain non-ASCII without specifying
+encoding. Run it as: C<perl Porting/checkpodencoding.pl>.
+
+=head2 F<cherrymaint>
+
+Command line tool to update cherrymaint; a tool for selecting commits from 
+blead to cherry-pick into stable perl versions.
+
+=head2 F<cmpVERSION.pl>
+
+Compare the current Perl source tree and a given tag for modules that have
+identical version numbers but different contents.
+
+=head2 F<config_H>
+
+This file is a sample F<config.h> file.  If you are unable to successfully run
+F<Configure>, copy this file to F<config.h> and edit it to suit your system.
+
+=head2 F<config_h.pl>
+
+Used when importing changes from F<metaconfig>.  This script reorders
+F<config_h.SH> after metaconfig.
+
+=head2 F<config.sh>
+
+This file is a sample F<config.sh> file.  F<config.sh> is normally
+produced by running the F<Configure> script. It holds all the definitions
+figured out by F<Configure>.  If you are unable to successfully run
+F<Configure> on your system, copy this sample file to F<config.sh>
+at the top of the perl source tree and edit it to suit your system.
+Then propagate those values by running C<Configure -S>.  This sample
+file is normally updated each time F<Configure> is updated.
+
+=head2 F<core-cpan-diff>
+
+Compare CPAN modules with their equivalent in core. 
+Originally based on App::DualLivedDiff by Steffen Mueller.
+
+=head2 F<corecpan.pl>
+
+Reports, in a perl source tree, which dual-lived core modules have not the
+same version than the corresponding module on CPAN.
+
+=head2 F<corelist-diff>
+
+Prints a table of differences between two Perl versions with respect to
+modules included in the distribution.
+
+=head2 F<corelist.pl>
+
+Generates info for Module::CoreList from this perl tree.
+
+=head2 F<corelist-perldelta.pl>
+
+Generates a list of the module changes for the Perl you are currently
+building.  Also generates a diff between the corelist sections of two
+F<perldelta*> files.
+
+=head2 F<epigraphs.pod>
+
+List of Perl release epigraphs.
+
+=head2 F<exec-bit.txt>
+
+This file contains a list of files that F<makerel> will ensure get an
+executable bit.
+
+=head2 F<exercise_makedef.pl>
+
+Brute force testing for F<makedef.pl>.
+
+=head2 F<expand-macro.pl>
+
+Expand C macros using the C preprocessor.
+
+=head2 F<findrfuncs>
+
+This script finds reentrant variants of functions used in an executable and
+shared objects.
+
+=head2 F<GitUtils.pm>
+
+This script contains the subroutine to generate a F<.patch file> for a
+committish (the SHA1 checksum of a commit, a number made of 40 hexadecimal
+digits which acts the internal unique identifier for this commit
+(lilypond.org).  Related file: F<make_dot_patch.pl>

+=head2 F<git-deltatool>
+
+This script, a rough draft, aids in generating a perldelta file
+from a series of git commits.

+id.
+
+=head2 F<git-make-p4-refs>
+
+This script creates a tag for every p4raw-id.
+
+=head2 F<Glossary>
+
+This file is built by F<metaconfig>. This file contains a description of all
+the shell variables whose value is determined by the Configure script. 
+It later gets incorporated into the pod for F<Config.pm>.
+
+=head2 F<how_to_write_a_perldelta.pod> 
+
+This file contains a specification as to how to write a perldelta pod.
+Related file: F<perldelta_template.pod>
+
+=head2 F<leakfinder.pl>
+
+This script executes every line in every file in the build directory and its
+subdirectories to determine if the number of SVs goes up and reports it as a
+leak to STDOUT.  WARNING! some harm could be done if a line contains something
+similar to C<`rm *`>.

+=head2 F<Maintainers>
+
+This script shows information about the maintainers of core files/modules.
+
+Related files: F<Maintainers.pl>, F<Maintainers.pm>

+at L<http://perl5.git.perl.org/perl.git/blob_plain/HEAD:/Porting/todo.pod>.
+The tasks we think are smaller or easier are listed first.  Anyone is welcome
+to work on any of these, but it's a good idea to first contact
+F<perl5-porters@perl.org> to avoid duplication of effort, and to learn from
+any previous attempts.

+I must here declare myself as someone who does not for a moment subscribe to
+the general view that a willingness to perform oneself is detrimental to the
+dignity of experimental philosophy. There is, after all, a clear distinction
+between labour carried out for financial reward, and that done for the
+improvement of mankind: to put it another way, Lower as a philosopher was
+fully my equal even if he fell away when he became the practising physician.
+I think ridiculous of certain professors of anatomy, who find it beneath
+them to pick up the knife themselves, but merely comment while hired hands
+do the cutting. Sylvius would never have dreamt of sitting on a dais reading
+from an authority while others cut E<0x2014> when he taught, the knife was
+in his hand and the blood spattered his coat. Boyle also did not scruple to
+perform his own experiments and, on one occasion in my presence, even showed
+himself willing to anatomise a rat with his very own hands. Nor was he less
+a gentleman when he had finished. Indeed, in my opinion, his stature was all

+No thought.
+  The boy extinguished. Only a place.
+  This place.
+  Motionless, the Pragma sat facing him, the bare soles of his feet flat against each other, his dark frock scored by the shadows of deep folds, his eyes as empty as the child they watched.
+  A place without breath or sound. A place of sight alone. A place without before or after . . . almost.
+  For the first lances of sunlight careered over the glacier, as ponderous as great tree limbs in the wind. Shadows hardened and light gleamed across the Pragma’s ancient skull.
+  The old man’s left hand forsook his right sleeve, bearing a watery knife. And like a rope in water, his arm pitched outward, fingertips trailing across the blade as the knife swung languidly into the air, the sun skating and the dark shrine plunging across its mirror back . . .
+  And the place where Kellhus had once existed extended an open hand—the blond hairs like luminous filaments against tanned skin—and grasped the knife from stunned space.
+  The slap of pommel against palm triggered the collapse of place into little boy. The pale stench of his body. Breath, sound, and lurching thoughts.
+  I have been legion . . .
+  In his periphery, he could see the spike of the sun ease from the mountain. He felt drunk with exhaustion. In the recoil of his trance, it seemed all he could hear were the twigs arching and bobbing in the wind, pulled by leaves like a million sails no bigger than his hand. Cause everywhere, but amid countless minute happenings—diffuse, useless.

+Once upon a time Trurl the constructor built an eight-story thinking
+machine.  When it was finished, he gave it a coat of white paint,
+trimmed the edges in lavender, stepped back, squinted, then added a
+little curlicue on the front and, where one might imagine the forehead
+to be, a few pale orange polkadots.  Extremely pleased with himself,
+he whistled an air and, as is always done on such occasions, asked it
+the ritual question of how much is two plus two.
+
+The machine stirred.  Its tubes began to glow, its coils warmed up,
+current coursed through all its circuits like a waterfall,
+transformers hummed and throbbed, there was a clanging, and a
+chugging, and such an ungodly racket that Trurl began to think of
+adding a special mentation muffler.  Meanwhile the machine labored on,
+as if it had been given the most difficult problem in the Universe to
+solve; the ground shook, the sand slid underfoot from the vibration,
+valves popped like champagne corks, the relays nearly gave way under
+the strain.  At last, when Trurl had grown extremely impatient, the
+machine ground to a halt and said in a voice like thunder: SEVEN!

+Preparation:
+
+Cut 16 Perl Onions into quarters and put them in a grill smoker rack
+or a perforated pan over a BBQ using hickory wood chips or Special
+Blend Smoker Bisquettes.  Smoke them for an hour and remove once they
+look golden brown.
+Let them cool and put them in the fridge (or freezer) until you are
+ready to create the soup.
+
+Ingredients:
+
+  16 diced, pre-smoked, Perl Onions
+  3 tbsp butter
+  1/4 cup olive oil
+  2 small garlic cloves, finely minced
+  1 tsp salt
+  1 tsp sugar
+  black pepper to taste
+  1 cup red wine
+  1/4 cup all purpose flour
+  6 cups of beef or vegetable stock
+  1 cup of thick cream (milk can be used as a substitute)
+
+Method:
+
+  Melt the butter in a pan and then add olive oil.
+  Heat and add the onions to caramelize over a medium-high heat for up
+    to half an hour.
+  Add the garlic, turn down the heat and cook for a further 5 minutes.
+  Add the salt, pepper and sugar.
+  Now add the red wine and reduce to a jam like consistency.
+  Add the flour, stir well and add the stock a cup at a time.
+  Simmer for 30 minutes, add the cream and heat to almost boiling.

+
+=cut
+
+=head1 DESCRIPTION
+
+This program, when C<require>d into other programs in the Perl 5 core
+distribution, provides functions useful during building and, secondarily,
+testing.
+
+As of this writing, the functions in this program are used in these other
+programs:
+
+    installman
+    installperl
+    pod/buildtoc
+    pod/perl.pod
+    Porting/new-perldelta.pl
+    Porting/pod_rules.pl
+
+Note:  Since these functions are used during the Perl build process, they must
+work with F<miniperl>.  That necessarily implies that these functions must not
+rely on XS modules, either directly or indirectly (e.g., C<autodie>).

+=head1 Tasks that need only a little Perl knowledge
+
+=head2 Fix POD errors in Perl documentation
+
+Perl documentation is furnished in POD (Plain Old Documentation); see
+L<perlpod>.  We also have a utility that checks for various errors in
+this documentation: F<t/porting/podcheck.t>.  Unfortunately many files
+have errors in them, and there is a database of known problems, kept in
+F<t/porting/known_pod_issues.dat>.  The most prevalent errors are lines
+too wide to fit in a standard terminal window, but there are more
+serious problems as well; and there are items listed there that are not
+in fact errors.  The task would be to go through and clean up the
+documentation.  This would be a good way to learn more about Perl.
+
 =head1 Tasks that only need Perl knowledge
 
+=head2 Classify bug tickets by type
+
+Known bugs in Perl are tracked by L<https://rt.perl.org/rt3> (which also
+includes Perl 6).  A summary can be found at
+L<https://rt.perl.org/rt3/NoAuth/perl5/Overview.html>.
+It shows bugs classified by "type".  However, the type of many of the
+bugs is "unknown".  This greatly lowers the chances of them getting
+fixed, as the number of open bugs is overwhelming -- too many to wade
+through for someone to try to find the bugs in the parts of
+Perl that s/he knows well enough to try to fix.  This task involves

+When a bug report is filed, it would be very helpful to have someone do
+a quick investigation to see if it is a real problem, and to reply to
+the poster about it, asking for example code that reproduces the
+problem.  Such code should be added to the test suite as TODO tests, and
+the ticket should be classified by type.  To get started on this task,
+look at the tickets that are marked as "New Issues" in

+=head2 Revisit the regex super-linear cache code
+
+Perl executes regexes using the traditional backtracking algorithm, which
+makes it possible to implement a variety of powerful pattern-matching
+features (like embedded code blocks), at the cost of taking exponential time
+to run on some pathological patterns.  The exponential-time problem is
+mitigated by the I<super-linear cache>, which detects when we're processing
+such a pathological pattern, and does some additional bookkeeping to avoid
+much of the work.  However, that code has bit-rotted a little; some patterns
+don't make as much use of it as they should.  The proposal is to analyse
+where the current cache code has problems, and extend it to cover those cases.
