$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
tar          try tar, gnutar, gtar, then tar without non-portable flags
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.

Send bug reports to <bug-automake@gnu.org>."
