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