      with is a Bash script that starts an interactive shell with where every
      command is prefixed using <program>.

      For example:

      $ with git
      git> add .
      git> commit -a -m "Committed"
      git> push

      Can also be used for compound commands.

      $ with java Primes
      java Primes> 1
      2
      java Primes> 4
      7

      And to repeat commands:

      $ with gcc -o output input.c
      gcc -o -output input.c>
      <enter>
      Compiling...
      gcc -o -output input.c>

      To execute a shell command proper prefix line with :.

      git> :ls

      You can also drop, add, and replace different commands.

      git> +add
      git add> <some file>
      git add> !commit
      git commit> <arguments and message>
      git commit> -
      git>

      To exit use either :q or :exit.
