My "hint" would be to get it working on one file first.  That's  
pretty easy.  You can do it with a single Regexp.  Then expand it to  
a recursive directory search.

How do you want to detect binary files?  By extension?  Regexp can  
probably help there too.

My "where to look advice" is the Regular Expression section (page 68)  
for the conversion, the Find library (page 679) for the directory  
traversal, and the OptionParser library (page 711) for the options  
you want to give yourself.

I'm not knowledgeable about packaging Ruby .exe files, but I know  
there are tools for this.  Check out AllInOneRuby, for example.

If you really need this fast and coding it isn't a requirement, I'm  
going to be blown away if a line ending conversion tool doesn't  
already exist in some form.

Hope that helps.
