+/**
+A replacement for getargs() and getconfig() which uses the <popt> library to parse
+both command-line arguments and configuration files. A specific configuration file
+may be specified using the --ConfigFile option. If one is not specified, then the
+configuration files at /etc/<cmd>rc and ~/.<cmd>rc will be loaded in that order (so
+user preferences will override the ones specified in /etc. Note: <cmd> is the
+basename() or argv[0] so one could run the same executeable through soft links to
+get different configuration files loaded for different instances of the same program.
+The ConfigFile option may only be used on the command-line. All other command-line
+options may also be specified in configuration files. <popt> aliases are enabled
+here so a user can define their own options in the /etc/popt or ~/.popt files.
+RETURN VALUE: 0 on success, non-zero on error
