Installs a bare repo into .cfg folder in home. The repo has my dot files for bash customizations. See repo for notes.

echo "Finished."
echo "We're using the curl-and-pipe method to run the install, so there is no script file to delete after execution. The script runs in memory and terminates when it's done, leaving no trace on the disk."
echo "Enjoy!"

updated again, no need for self delete. see echo at end of script.

special handling for .extra file (stop tracking for user to make private local machine changes)
