   3 # Configures and builds nmh.
   4 # * If this script is not invoked from an nmh source directory, it
   5 #   will attempt to download the nmh sources.
   6 # * This script retrieves configuration from the first existing nmh
   7 #   installation on your $PATH, if any.
   8 # * Unless the -y option is provided, this script then interactively
   9 #   walks you through confirmation of common configuration settings.
  10 #
  11 # This file can be downloaded and immediately run using, e.g.,
  12 #   wget http://git.savannah.gnu.org/cgit/nmh.git/plain/build_nmh
  13 #   sh build_nmh
  14 #
  15 # Typical usage:
  16 # The first time you invoke this script, use the -i option to install
  17 # nmh in the specified location.  The script will walk you through the
  18 # common nmh configuration settings.  The -v option will cause display
  19 # of brief progress indicators.  Be sure to add the bin directory of
  20 # the install location to your $PATH, if not already there.
  21 # Subsequently, invoke this script with the -y option, to use the
  22 # relevant configuration settings from the installed nmh without
  23 # confirmation.
  24 #
  25 # Option summary:
  26 #   First time use:
  27 #     -b <branch> to specify branch to check out, only if downloading sources
  28 #     -i to install nmh
  29 #     -v to display progress
  30 #   Subsequent uses, assuming installed nmh bin directory is on $PATH:
  31 #     -y to accept all configuration options without confirmation
  32 #   Output control:
  33 #     -l <logfile name>, default 'build_nmh.log', - for stdout/stderr
  34 #   Advanced/developer use:
  35 #     -c to run 'make distcheck' instead of 'make check'
  36 #     -d to build nmh with asserts enabled and optimization disabled
  37 #     -s to use 'make superclean': requires recent autoconf and automake,
  38 #        see docs/README.developers
  39 #     -r to build rpm
  40 #
  41 # To disable colorization of the test summary, either unset the TERM
  42 # environment variable or set it to dumb, e.g., TERM=dumb build_nmh.
  43 #
  44 # See the nmh MACHINES file for build prerequisites.  In addition, the rpmbuild
  45 # is required to be available if the -r option is used.
