CR2CRLF is a C++ program which converts carriage returns to carriage returns + linefeeds.
I constantly run into problems, when transferring a file from one system to another, involving different conventions for ending a line of text.
It is my understanding that the following "conventions" apply:
While your file transfer program will usually transfer a text file in such a way that that carriage control is properly translated, this sometimes doesn't happen, especially if the text file is transferred "verbatim", that is, as though it were a binary file.
In such a case, CR2CRLF is the correct program to use if you want to convert a Macintosh (pre OSX) text file to a PC text file, since it will replace each occurrence of CR by CR+LF.
