In the ackrc file I added a definition for a new file type, '.F', which is for
the pre-compile Fortran files in WRF. Once I did that, I created an alias, in
the bash_aliases file, for the command 'ack --type=F', where '--type=F' tells
ack to only search for this new type I created, i.e. the '.F' type. I named
this alias 'fack'. Aren't I so clever? :-)
