cvswdiff

[Richard Atterer <deb-www@list02.atterer.net>]

Hi translators,

the attached script might help to separate reformatting changes from
changes in wording. Basically, it's just a wrapper which calls CVS to
get the revisions and then passes the text to wdiff.

cvswdiff filename
        Outputs a wdiff between the most recent revision and the
        working copy.

cvswdiff 1.9 filename
        Outputs a wdiff between revision 1.9 and the working copy.

cvswdiff 1.9 1.12 filename
        Outputs a wdiff between the revisions 1.9 and 1.12.

Cheers,

  Richard
