The package FOO needs package BAR. Consider \NeedsTeXFormat. If FOO changes, then you may or may not have to also change BAR. If BAR changes, you only need to change BAR. Using \verify_package, if FOO changes, then you only have to change FOO. If BAR changes, then you have to change FOO and BAR. What I believe the LaTeX people want is the second result. If someone changes some file deep down within LaTeX, then they want you to have to change the LaTeX kernel. If someone changes the LaTeX kernel, then they don't care what happens to the internals. This is all independent of the licensing scheme. The license under consideration for \NeedTeXFormat seem to want to force a change in FOO if BAR changes. I would vastly prefer technical, rather than legal means. It does make LaTeX more fragile. That seems to be what the LaTeX people want. If you fiddle with any part, then everything that uses that breaks. Regards, Walter Landry [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
