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.

36  * miniperlmain.c is generated by running regen/miniperlmain.pl, while
37  * perlmain.c is built automatically by Makefile (so the former is
38  * included in the tarball while the latter isn't).
