Before committing ~~~~~~~~~~~~~~~~~ All source files need to be passed through indent command. Follow http://wiki.sugarlabs.org/go/Activity_Team/Sugar_Lint instructions and especially "Lint files before committing" section. Otherwise just call indent command with settings [1]. Send patches ~~~~~~~~~~~~ Create your patches using "git format" command and send them to all maintainers from AUTHORS file. The easiest way it just using "git send-email" command.
