Re: Ignoring whitespace and CR/LF when checking into repository

[Antony Paul]

Does making files binary using -kb compromises any other
functionality. Some developers want CVS to merge changes
automatically. If the file is treated as binary will it merge ?.

Does any one have an example of a commitinfo filter which can identify
ASCII files ?

Using commitinfo does requires a server ?.
