In general, the CVS log command can be used to find changes between two tags, or made after a tag. In practice, it's not so easy, especially when files are branched. I have recently spent about three days on this problem. Although I don't have a tool that does exactly what you want, I do have example code written in Perl that uses "cvs log" which is a big part of the problem. The link http://devguy.com/pctk/hist.htm points to several files. One in particular is "Perl module source code" -- CVS.pm contains a function called MakeChangeLog which parses the output of "cvs log." If you have a Windows machine and install the executables via the link "Executables install," the program "dgchangelog.exe" is a shell for this function. Likewise, you can click on the "Perl source code" link to get the Perl source code for dgchangelog. I have only tested this on Windows but in theory the code is multi-platform. Example usage: c:\cvs>dgchangelog tagname "" Sandbox c:/cvs This outputs all changes made _after_ tagname in the same branch, up to the actual revision that's checked out in your sandbox. It is theoretically possible to parse the output of this script to then pipe to "cvs checkout". You can provide a second tag name but the output is generally unreliable in this case. Or, you can modify the source code to your heart's content if you are a Perl jockey. Hope this helps.
