# Library Browser Help (Versions View)

Note: please forgive the crude diagrams and terse descriptions in this help file. It is only a first draft.

The left chooser contains a list of versions for a particular branch indexed by the browser. A version is a sequence of revisions, presumably intended to culminate in the release having the version's version number.

Clicking on a version presents you with a list of revisions within that version. Each revision is considered a "patch level" -- usually a set of changes made to the previous revision. In the revision list, you can see who created each revision and on what date. You can see the "Summary:" line from the log message for the revision.

There are various links in the revision list:

- log entry shows you the complete text of the log entry for a revision.
- patch set shows you a list of all the changes made in that revision.
- source lets you explore a complete source tree for the revision.
- files shows you a list of files in the revision. Clicking on a particular file takes you to a history of just that file: information about which revisions contain changes to that file.
- ChangeLog shows you the (automatically generated) ChangeLog entry associated with the revision.
- details shows you a expanded form of the revision list, with many more details added to the list.
