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