POSIX-conformant command-line option parser (plus long options)

POSIX-conformant command-line option parser (plus long options)

Use it like this:

import pgetopt

ovc, args = pgetopt.parse({
# opt: (name,          type, default value, helptext[, arg name])
  "s": ("schmooze",    bool, 0,    "increase schmooziness"),
  "o": ("output_file", str,  None, "output file (or stdout)", "NAME"),
  "n": ("repetitions", int,  3,    "number of repetitions"),
  "d": ("debug",       str, [],    "debug topics", "DEBUG_TOPIC"),
# keyword:        value
  "_arguments":   ("string_to_print", "..."),
  "_help_header": "print a string a number of times",
  "_help_footer": "This is just an example program.",
})

On return, the option value container ovc has the following fields:
ovc.schmooze: the number of -s options counted,
ovc.output_file: the parameter of -o or --output-file, or None
ovc.repetitions: the parameter of -n or --repetitions, or 3
ovc.debug: a list with all parameters given to -d or --debug

Options -h, --help, -?, --usage are installed by default and print a help message or a brief usage message, respectively.

args holds the remaining arguments behind the last option.

Call help(pgetopt) for details.
