I’ve had to add another bit to yyhelp to make my everyday coding more convenient, so it got support for git-svn(1). The yypull and yypushpull commands will now detect a git(7) repository set up with git-svn, and unless the repository also has a regular git upstream, pulling and pushing will be carried out via git-svn rebase and git-svn dcommit. yyinfo shows the update method being used for a repository and also displays the SVN HEAD revision now if any. That, plus miscellaneous changes make version 0.6 of yyhelp:
Overview of Changes in YummyYummySourceControl-0.6: * for git-svn repositories, use rebase and dcommit to pull and push * fixed argument parsing for yybranch and yybranchdel * support revision argument for yydiff * check revision argument to yywarp
