30 * crunched_main.c - main program for crunched binaries, it branches to a
31 * particular subprogram based on the value of argv[0]. Also included
32 * is a little program invoked when the crunched binary is called via
33 * its EXECNAME. This one prints out the list of compiled-in binaries,
34 * or calls one of them based on argv[1]. This allows the testing of
35 * the crunched binary without creating all the links.
