Labeled hierarchy

This script renders the version of a page specified with either a label or a time specification, given as parameters. Links in this page are modified to use the script itself, and the same arguments. In case only a label was given, it passes on a time specification based on the time when the label type was last locked.

Examples of usage: v CGS_1.00 and version current on November 7, 2001 of Clearcase Global Service.

Assumptions/decisions:

• Files not bearing the label are treated via the time specification.
• The label type or the time stamp is added to the title line.
• It is assumed that the label is found on each directory in the access path (e.g. applied with apply_label on a derived object).
  • This allows to bypass the doc config spec, and is thus robust to changes.
  • This assumption is usually not satisfied by floating labels.
  • Note that the path used for the file parameter may differ from the one accessible by default.
• Non-local links, explicitly using any kind of scheme (http: etc.) are left untouched.
• Internal links (within a page) are ignored (dropped). The reason is that I don't know how to tell the browser to position itself within a generated page.
