Request for option to show version to generate help for all command line tools

[Michael Wood-Vasey]

It would be useful for all IPP and PsLib (and other software under "our" control) to report the version information and help information. E.g.,

addstar -v
addstar --version

prints the version number (and possibly other relevant version/compilation-related information) to STDOUT and exits.

addstar -h
addstar --help

For example:

[wwoodvas@calm] gcc --version
powerpc-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)

The choice of the exact option specification is up to system standardization. E.g., perhaps double - options such as --version are not supported by choice.

P.S. I had to choose some component to submit this bug report, but really this applies to all of PSLib and all of IPP software.
