they can find the p4 branches in refs/heads.
--max-changes <n>::
- Limit the number of imported changes to 'n'. Useful to
- limit the amount of history when using the '@all' p4 revision
- specifier.
+ Import at most 'n' changes, rather than the entire range of
+ changes included in the given revision specifier. A typical
+ usage would be use '@all' as the revision specifier, but then
+ to use '--max-changes 1000' to import only the last 1000
+ revisions rather than the entire revision history.
+
+--changes-block-size <n>::
+ The internal block size to use when converting a revision
+ specifier such as '@all' into a list of specific change
+ numbers. Instead of using a single call to 'p4 changes' to
+ find the full list of changes for the conversion, there are a
+ sequence of calls to 'p4 changes -m', each of which requests
+ one block of changes of the given size. The default block size
+ is 500, which should usually be suitable.
