CRRM is a C++ program which removes carriage returns from a file.
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, CRRM is the correct program to use if you want to convert a PC text file to a UNIX text file, since it will replace each occurrence of CR+LF by LF.
