This option is normally not useful when CVS is used. This option is useful to ignore differences due to keyword substitution when comparing different revisions of a file. This can be useful for binary file formats that cannot tolerate any changes to substrings that happen to take the form of keyword strings. However, further keyword substitution cannot be performed once the keyword names are removed, so this option should be used with care. Once you export the file the history information might be useless anyhow.
Conflicts often result from the merging operation.
If that is done the information from cvs log will not be consistent with the information inside the file. This may or may not be a problem in real life. That way the long list of change messages will not interfere with everyday source file browsing. Go to the previous , next section.
