25/* This file contains the main() function for the perl interpreter.
26 * Note that miniperlmain.c contains main() for the 'miniperl' binary,
27 * while perlmain.c contains main() for the 'perl' binary. The typical
28 * difference being that the latter includes Dynaloader.
29 *
30 * Miniperl is like perl except that it does not support dynamic loading,
31 * and in fact is used to build the dynamic modules needed for the 'real'
32 * perl executable.
33 *
34 * The content of the body of this generated file is mostly contained
35 * in Miniperl.pm - edit that file if you want to change anything.
36 * miniperlmain.c is generated by running regen/miniperlmain.pl.pl, while
37 * perlmain.c is built automatically by Makefile (so the former is
38 * included in the tarball while the latter isn't).
