Display the differences between two revisions or paths.
usage: 1. diff [-c M | -r N[:M]] [TARGET[@REV]...]
2. diff [-r N[:M]] --old=OLD-TGT[@OLDREV] [--new=NEW-TGT[@NEWREV]] \
[PATH...]
3. diff OLD-URL[@OLDREV] NEW-URL[@NEWREV]
1. Display the changes made to TARGETs as they are seen in REV between
two revisions. TARGETs may be all working copy paths or all URLs.
If TARGETs are working copy paths, N defaults to BASE and M to the
working copy; if URLs, N must be specified and M defaults to HEAD.
The '-c M' option is equivalent to '-r N:M' where N = M-1.
Using '-c -M' does the reverse: '-r M:N' where N = M-1.
2. Display the differences between OLD-TGT as it was seen in OLDREV and
NEW-TGT as it was seen in NEWREV. PATHs, if given, are relative to
OLD-TGT and NEW-TGT and restrict the output to differences for those
paths. OLD-TGT and NEW-TGT may be working copy paths or URL[@REV].
NEW-TGT defaults to OLD-TGT if not specified. -r N makes OLDREV default
to N, -r N:M makes OLDREV default to N and NEWREV default to M.
3. Shorthand for 'svn diff --old=OLD-URL[@OLDREV] --new=NEW-URL[@NEWREV]'
Use just 'svn diff' to display local modifications in a working copy.
