GHCi does not have a :source command to load further .ghci files

[SamB]

This makes it difficult to put useful GHCi commands under version control (in such a way that they can be used) without having everyone share a common .ghci file for a project. For example, see  http://comments.gmane.org/gmane.comp.lang.haskell.jhc/101

:def source readFile

put that in your .ghci, and you're ready to go (check the ghci user guide on :def, :cmd, etc.). you might also find this interesting:

 getting more out of ghci

Wow, that simple???

What needs to be done to get this in ":?" output? (It should be in the manual, at least...)
