$0 [OPTION]... PROGRAM [ARGUMENT]...

Handle 'PROGRAM [ARGUMENT]...' for when PROGRAM is missing, or return an

error status if there is no known handling for PROGRAM.

Options:

-h, --help display this help and exit

-v, --version output version information and exit

--run try to run the given command, and emulate it if it fails

Supported PROGRAM values:

aclocal touch file 'aclocal.m4'

autoconf touch file 'configure'

autoheader touch file 'config.h.in'

autom4te touch the output file, or create a stub one

automake touch all 'Makefile.in' files

bison create 'y.tab.[ch]', if possible, from existing .[ch]

flex create 'lex.yy.c', if possible, from existing .c

help2man touch the output file

lex create 'lex.yy.c', if possible, from existing .c

makeinfo touch the output file

yacc create 'y.tab.[ch]', if possible, from existing .[ch]

Version suffixes to PROGRAM as well as the prefixes 'gnu-', 'gnu', and

'g' are ignored when checking the name.
