- =head1 NAME
-
- ExtUtils::Miniperl, writemain - write the C code for perlmain.c
-
- =head1 SYNOPSIS
-
- C<use ExtUtils::Miniperl;>
-
- C<writemain(@directories);>
-
- =head1 DESCRIPTION
-
- This whole module is written when perl itself is built from a script
- called minimod.PL. In case you want to patch it, please patch
- minimod.PL in the perl distribution instead.
-
- writemain() takes an argument list of directories containing archive
- libraries that relate to perl modules and should be linked into a new
- perl binary. It writes to STDOUT a corresponding perlmain.c file that
- is a plain C file containing all the bootstrap code to make the
- modules associated with the libraries available from within perl.
-
- The typical usage is from within a Makefile generated by
- ExtUtils::MakeMaker. So under normal circumstances you won't have to
- deal with this module directly.
