1398 ## ------ ##
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.
1434
1435 ## -------------- ##

1441 # option parser.
1442
1443 # The usage line for option parsing errors and the start of '-h' and
1444 # '--help' output messages. You can embed shell variables for delayed
1445 # expansion at the time the message is displayed, but you will need to
1446 # quote other shell meta-characters carefully to prevent them being
1447 # expanded when the contents are evaled.

6334    - Space and tab are interpreted as delimiters. They are not treated as
6335      delimiters if they are surrounded by double quotes: "...".
6336    - Unescaped double quotes are removed from the input. Their only effect is
6337      that within double quotes, space and tab are treated like normal
6338      characters.
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):
6342        \" -> "
