.. instead of copying it all the time; gnulib-tool and bootstrap are now ready to do this correctly. Bootstrap upstream is now dual-licensed as MIT/GPLv2+; so the sources are redistributed automatically under GPLv3+ license in in libtool project. * .gitmodules (bootstrap): New submodule. * bootstrap.conf (local_gl_dir): Renamed to local_gl_path. (local_gl_path): Renamed from local_gl_dir. Two sub-directories are now mentioned as two --local-dir's are used. (gnulib_git_submodules): New option to automatically clone the bootstrap git submodule. * build-aux/ltmain.in (libtool_options_prep) (libtool_parse_options): Changing function exit status is not needed with new options-parser. * libtoolize.in: Don't func_quote when it is not necessary, don't set the function return value. * gl-mod/bootstrap: New git submodule. * gl/build-aux/bootstrap.in, gl/build-aux/extract-trace, gl/build-aux/funclib.sh, gl/build-aux/inline-source, gl/build-aux/options-parser, gl/doc/bootstrap.texi, gl/modules/all-shells-tests, gl/modules/bootstrap, gl/modules/extract-trace, gl/modules/funclib.sh, gl/modules/funclib.sh-tests, gl/modules/inline-source gl/modules/options-parser, gl/modules/options-parser-tests, gl/tests/test-all-shells.sh, gl/tests/test-funclib-quote.sh gl/tests/test-option-parser-helper, gl/tests/test-option-parser.sh: Files removed, those are automatically pulled from upstream now. * bootstrap: Sync with upstream.

# Bootstrap an Autotooled package from checked-out sources.

## ------ ##
|
||
## Usage. ##
|
||
## ------ ##
|
||
|
||
# Most GNUish projects do not keep all of the generated Autotool
|
||
# files under version control, but running all of the right tools
|
||
# with the right arguments, in the correct order to regenerate
|
||
# all of those files in readiness for configuration and building
|
||
# can be surprisingly involved! Many projects have a 'bootstrap'
|
||
# script under version control to invoke Autotools and perform
|
||
# other assorted book-keeping with version numbers and the like.
|
||
#
|
||
# This bootstrap script aims to probe the configure.ac and top
|
||
# Makefile.am of your project to automatically determine what
|
||
# the correct ordering and arguments are and then run the tools for
|
||
# you. In order to use it, you can generate an initial standalone
|
||
# script with:
|
||
#
|
||
# gl/build-aux/inline-source gl/build-aux/bootstrap.in > bootstrap
|
||
#
|
||
# You should then store than script in version control for other
|
||
# developers in you project. It will give you instructions about
|
||
# how to keep it up to date if the sources change.
|
||
#
|
||
# See gl/doc/bootstrap.texi for documentation on how to write
|
||
# a bootstrap.conf to customize it for your project's
|
||
# idiosyncracies.

# quotes backslashified. Available only if 'unquoted' is specified.

# ----------------
|

# 'eval' (default)
|

# - escape shell special characters
|
||
# 'expand'
|
||
# - the same as 'eval'; but do not quote variable references
|
||
# 'pretty'
|
||
# - request aesthetic output, i.e. '"a b"' instead of 'a\ b'. This might
|
||
# be used later in func_quote to get output like: 'echo "a b"' instead
|
||
# of 'echo a\ b'. This is slower than default on some shells.
|
||
# 'unquoted'
|
||
# - produce also $func_quote_arg_unquoted_result which does not contain
|
||
# wrapping double-quotes.

## Usage. ##
|
||
## ------ ##
|
||
|
||
# This file is a library for parsing options in your shell scripts along
|
||
# with assorted other useful supporting features that you can make use
|
||
# of too.
|
||
#
|
||
# For the simplest scripts you might need only:
|
||
#
|
||
# #!/bin/sh
|
||
# . relative/path/to/funclib.sh
|
||
# . relative/path/to/options-parser
|
||
# scriptversion=1.0
|
||
# func_options ${1+"$@"}
|
||
# eval set dummy "$func_options_result"; shift
|
||
# ...rest of your script...
|
||
#
|
||
# In order for the '--version' option to work, you will need to have a
|
||
# suitably formatted comment like the one at the top of this file
|
||
# starting with '# Written by ' and ending with '# Copyright'.
|
||
#
|
||
# For '-h' and '--help' to work, you will also need a one line
|
||
# description of your script's purpose in a comment directly above the
|
||
# '# Written by ' line, like the one at the top of this file.
|
||
#
|
||
# The default options also support '--debug', which will turn on shell
|
||
# execution tracing (see the comment above debug_cmd below for another
|
||
# use), and '--verbose' and the func_verbose function to allow your script
|
||
# to display verbose messages only when your user has specified
|
||
# '--verbose'.
|
||
#
|
||
# After sourcing this file, you can plug in processing for additional
|
||
# options by amending the variables from the 'Configuration' section
|
||
# below, and following the instructions in the 'Option parsing'
|
||
# section further down.
