Bring clp into the autotools-update world. Very rough. Builds and passes
unit test but non-doxygen documentation and examples are untested.

1399## Usage. ##
1400## ------ ##
1401
1402# This file is a library for parsing options in your shell scripts along
1403# with assorted other useful supporting features that you can make use
1404# of too.
1405#
1406# For the simplest scripts you might need only:
1407#
1408#   #!/bin/sh
1409#   . relative/path/to/funclib.sh
1410#   . relative/path/to/options-parser
1411#   scriptversion=1.0
1412#   func_options ${1+"$@"}
1413#   eval set dummy "$func_options_result"; shift
1414#   ...rest of your script...
1415#
1416# In order for the '--version' option to work, you will need to have a
1417# suitably formatted comment like the one at the top of this file
1418# starting with '# Written by ' and ending with '# warranty; '.
1419#
1420# For '-h' and '--help' to work, you will also need a one line
1421# description of your script's purpose in a comment directly above the
1422# '# Written by ' line, like the one at the top of this file.
1423#
1424# The default options also support '--debug', which will turn on shell
1425# execution tracing (see the comment above debug_cmd below for another
1426# use), and '--verbose' and the func_verbose function to allow your script
1427# to display verbose messages only when your user has specified
1428# '--verbose'.
1429#
1430# After sourcing this file, you can plug processing for additional
1431# options by amending the variables from the 'Configuration' section
1432# below, and following the instructions in the 'Option parsing'
1433# section further down.

6339   - Backslashes not followed by double quotes are not special.
6340   - But 2*n+1 backslashes followed by a double quote become
6341     n backslashes followed by a double quote (n >= 0):
