+.Sh NAME
+.Nm prebind
+.Nd cache symbol lookup information to speed up dynamic linking
+.Sh SYNOPSIS
+.Nm prebind
+.Op Fl mv
+.Op Ar file/dir ...
+.Sh DESCRIPTION
+.Nm
+parses each of the specified files or directories and processes each ELF file
+(ELF file found in the directory) and the associated
+.Dv DT_NEEDED
+libraries,
+and writes symbol resolution hint information to each binary and library.
+.Pp
+.Nm
+will add data to the programs specified and any libraries they reference
+to speed up dynamic linking.
+Since version information is stored in the libraries to validate the
+prebind info, running
+.Nm
+on a subset of programs it was previously
+run on will invalidate the prebind info for those excluded binaries.
+The
+.Fl m
+option will preserve the old prebind info in any library if present.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl m
+Merge into existing prebound libraries.
+This prebinds new binaries without modifying or updating the libraries
+(if prebind data is present), allowing old prebound binaries to continue
+to use the old prebind data.
+.It Fl v
+Be verbose when running
+.Nm :
+prints out information about the file/library that is being processed.

+.Sh SEE ALSO
+.Xr ld.so 1 ,
+.Xr prebind_strip 8
+.Sh STANDARDS
+None
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Ox 4.0 .
+.Nm
+is based loosely on Prelinking, however prelink removes the security
+feature of libraries appearing in random order on each invocation, thus
+it was incompatible with
+.Ox Ns 's
+goals.
+.Nm
+was written as an attempt to improve the speed of dynamic linking
+without the penalty of loss of security features.
+.Sh BUGS
+Prebind uses a lot of memory depending on how many files/libraries
+are being processed.
+Handling of binaries where a required library has been removed is poor.
