gemspec

#!/usr/bin/env ruby
# Usage: gemspec [-s] GEMNAME
#
# Prints a basic gemspec for GEMNAME based on your git-config info.
# If -s is passed, saves it as a GEMNAME.gemspec in the current
# directory. Otherwise prints to standard output.
#
# Once you check this gemspec into your project, releasing a new gem
# is dead simple:
#
# $ gem build GEMNAME.gemspec
# $ gem push GEMNAME-VERSION.gem
#
# Wants you to have a "lib/GEMNAME/version.rb" file in your project
# which sets the GEMNAME::VERSION constant.
