I am talking here about taking (for example) a perl program with Mac OS 
newlines, and making it run under Unix perl.  In order for that to happen, 
you need to translate all the CRs to LFs.  That would include the CRs in the 
heretext, as well as in every literal string.

One of the main points of this is that some people will want the same files 
to be used in more than one context, such as sharing code between Windows 
and Unix perl over NFS, or sharing code between perl on Mac OS X and MacPerl 
under Mac OS or Classic.  Right now, the only solution is to make copies, as 
you suggest.
