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. - - -## ================================================================== ## -## ## -## DO NOT EDIT THIS FILE, CUSTOMIZE IT USING A BOOTSTRAP.CONF ## -## ## -## ================================================================== ## - -## ------------------------------- ## -## User overridable command paths. ## -## ------------------------------- ## - -# All uppercase denotes values stored in the environment.
