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