# Configures and builds nmh.
-# * This script must be invoked from an nmh source directory.
+# * If this script is not invoked from an nmh source directory, it

# * This script retrieves configuration from the first existing nmh
-# installation on your $PATH, if any, as well as any $EDITOR/$VISUAL
-# and $PAGER environment variable settings.
+# installation on your $PATH, if any.
# * Unless the -y option is provided, this script then interactively

#
+# This file can be downloaded and immediately run using, e.g.,
+# wget http://git.savannah.gnu.org/cgit/nmh.git/plain/docs/contrib/build_nmh
+# sh build_nmh

# Typical usage:
# The first time you invoke this script, use the -i option to install
# nmh in the specified location. The script will walk you through the
#
# Option summary:
# First time use:
+# -b <branch> to specify branch to check out, only if downloading sources
# -i to install nmh
# -v to display progress
# Subsequent uses, assuming installed nmh bin directory is on $PATH:
# -y to accept all configuration options without confirmation
# Output control:
-# -l <logfile name>, default 'build_nmh.log'
+# -l <logfile name>, default 'build_nmh.log', - for stdout/stderr
# Advanced/developer use:
# -c to run 'make distcheck' instead of 'make check'
# -d to build nmh with debug enabled
# ncurses-devel
# cyrus-sasl-devel, if using sasl
# openssl-devel, if using TLS
+# libcurl-devel, if using oauth
# autoconf and automake, with -s (see docs/README.developers for versions)
# rpm-build, with -r
