package.sh

#!/bin/bash
#
# This script generates RPM and debian packages.
#
# Usage: ./package.sh [VERSION_STRING]
#
#   VERSION_STRING: version string for deb and RPM packaes.
#                   If ommited (recommended), it defaults to
#                   `git describe --tag | sed 's/^v//'`
#
# Build ependencies:
#   In short, do the following on Ubuntu based distribution to install
#   build dependencies.
#
#   $ sudo apt-get install -y rubygems rpm ruby-ronn && sudo gem install fpm
#
#   Here's list of dependencies:
#
#   * fpm (https://github.com/jordansissel/fpm):
#       This enables us to produce both RPM and debian packages easily
#       withough requiring details about their packaging systems
#
#   * rpm: of course rpmbuild is needed to produce RPM packages
#
#   * ronn: a tool to produce man pages from markdown

set -e

# Get version number from command line or defaults to use git describe
pkgver=$1
if [ "$pkgver" == "" ]; then
    pkgver=$(git describe --tag | sed 's/^v//')
