+=head1 NAME
+
+ExtUtils::Miniperl - write the C code for miniperlmain.c and perlmain.c
+
+=head1 SYNOPSIS
+
+    use ExtUtils::Miniperl;
+    writemain(@directories);
+    # or
+    writemain($fh, @directories);
+    # or
+    writemain(\$filename, @directories);
+
+=head1 DESCRIPTION
+
+C<writemain()> takes an argument list of zero or more directories
+containing archive
+libraries that relate to perl modules and should be linked into a new
+perl binary. It writes a corresponding F<miniperlmain.c> or F<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.
+If the first argument to C<writemain()> is a reference to a scalar it is
+used as the filename to open for output. Any other reference is used as
+the filehandle to write to. Otherwise output defaults to C<STDOUT>.
+
+The typical usage is from within perl's own Makefile (to build
+F<perlmain.c>) or from F<regen/miniperlmain.pl> (to build miniperlmain.c).
+So under normal circumstances you won't have to deal with this module
+directly.
