## DO NOT EDIT - This file generated from build-aux/bootstrap.in

# Bootstrap an Autotooled package from checked-out sources.

# Originally written by Paul Eggert. The canonical version of this
# script is maintained as build-aux/bootstrap in gnulib, however, to
# be useful to your project, you should place a copy of it under
# version control in the top-level directory of your project. The
# intent is that all customization can be done with a bootstrap.conf
# file also maintained in your version control; gnulib comes with a
# template build-aux/bootstrap.conf to get you started.
# Please report bugs or propose patches to bug-gnulib@gnu.org.
## ------ ##
## 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.

# All uppercase denotes values stored in the environment. These
# variables should generally be overridden by the user - however, we do
# set them to 'true' in some parts of this script to prevent them being
# called at the wrong time by other tools that we call ('autoreconf',
# for example).
#
# We also allow 'LIBTOOLIZE', 'M4', 'SHA1SUM' and some others to be
# overridden, and export the result for child processes, but they are
# handled by the function 'func_find_tool' and not defaulted in this
# section.
