I thought I could remove files from Git pretty easily with essentially :
$ git rm myfile.php $ git commit -m "Removing a file"
But I was getting this error upon commit : "Could not open input file myfile.php"
This is how I got it to work. The Git Cheat Sheet (http://cheat.errtheblog.com/s/git) described this as "Commit the absence of myfile.txt to the project"
$ git rm --cached myfile.php $ git commit -m "Removing a file"
