These are a few tools that I have written to make my life easier. They are nothing special but I find them useful... You might too.

• grant.rsa.login.sh
  Add an RSA/DSA key to a remote server
• revoke.rsa.login.sh
  remove an RSA/DSA key from a remote server
• mmmake.pl
  A handy tool to build source code from many different types of project. I Built it with the idea in mind that for most projects I could just run this and whatever standard build type they expected it would get detected and built.
• tgz.pl
  General purpose extraction tool. The primary motivation behind this one was that I got tired of writing for loops to unzip a list of archives. And this way I don't even have to think about what type of file I am working with.
