[ale] Mass changing of file extension

[jslozier at gmail.com (Jay Lozier)]

Hi,

I saw a question about importing a *.tsv (tab delimited text files) into
a spreadsheet. The problem is *.tsv are unusual while *.csv are common.

My question is how does one change the file extension of many *.tsv to
*.csv files?
