Cygwin but not really question

To extend the OS X's base Unix environment to be more Linux-like -- or 
Cygwin-like, if you prefer -- install Fink: http://fink.sf.net/  This is 
an APT-based packaging project which pulls in a lot of stuff that you 
find Linux and Cygwin, which was left out of OS X.  There is a dos2unix 
package:

	http://pdb.finkproject.org/pdb/package.php/dos2unix

So, after Fink is installed and configured for the first time, you just 
say "fink install dos2unix", and there you are.  You can use Bash 
aliases to get 'd2u' and 'u2d' if you don't want to retrain your 
fingers.  I find 'dos2unix' and 'unix2dos' a little more common.

Some people prefer MacPorts (http://www.macports.org/) which does much 
the same thing.  I happen to have started with Fink and have been happy 
with it, so haven't bothered to even try MacPorts.
