-v, --version output version information and exit

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

Supported PROGRAM values:

autoconf touch file 'configure'

autoheader touch file 'config.h.in'

automake touch all 'Makefile.in' files

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

'g' are ignored when checking the name.
