Use mercurial instead of git in a gem generated by bundle gem

new_hg_gem.sh

#! /bin/sh
 
set -e
 
bundle gem $1 
cd $1
 
rm -rf .git
mv .gitignore .hgignore
 
sed -i -e "1s/^/syntax: glob\n/" .hgignore

sed -i 's|git ls-files -z.*|hg manifest -q\`.split("\\n")|' $1.gemspec
sed -i "s/end$/  spec.add_development_dependency 'rspec', '~> 1.3'\nend/" $1.gemspec


sed -i -e "/MIT/d" $1.gemspec
sed -i -e "/description/d" $1.gemspec
sed -i "s/TODO:.*\}/$1}/" $1.gemspec

mkdir -p "spec/$1"
cat > spec/spec_helper.rb <<EOF
require '$1'
EOF

 
hg init
hg addremove

It is not possible to make a Pull Request for a Gist, so here is mine, where the files inside the test|spec|features folders are automatically removed from the *.gemspec file.
