   3 # JHBuild configuration script.
   4 #
   5 # For installation instructions please refer to the JHBuild manual:
   6 #   yelp /jhbuild-source-dir/doc/C/index.docbook
   7 #
   8 # Or refer to the on-line JHBuild manual at:
   9 #
  10 #  http://library.gnome.org/devel/jhbuild/stable/getting-started.html.en
  11 #
  12 # Usage:
  13 # ./autogen.sh [OPTION]
  14 #    Available OPTION are:
  15 #      --simple-install   Configure without using autotools. This setting is
  16 #                         set automatically if autotools and yelp-tools
  17 #                         are not installed.
  18 #      --prefix=PREFIX    Install JHBuild to PREFIX. Defaults to ~/.local
  19 #
  20 # If autotools and yelp-tools are available, this configuration script
  21 # will configure JHBuild to install via autotools.
  22 #
  23 # If autotools and yelp-tools are not available, this configuration
  24 # script will configure JHBuild to install via a plain Makefile.
  25 #
  26 # autogen.sh is used to configure JHBuild because the most common way to obtain
  27 # JHBuild is via git and a 'configure' should not be checked into git.
  28 #
  29 # autogen.sh supports i18n using the package gettext. If gettext is not
  30 # available english is used. To enable i18n autogen.sh builds mo files from po
  31 # files using po/Makefile.plain. The mo files are in $srcdir/mo.
