Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
convert: introduce --full for converting all files Convert will normally only process files that were changed in a source revision, apply the filemap, and record it has a change in the target repository. (If it ends up not really changing anything, nothing changes.) That means that _if_ the filemap is changed before continuing an incremental convert, the change will only kick in when the files it affects are modified in a source revision and thus processed. With --full, convert will make a full conversion every time and process all files in the source repo and remove target repo files that shouldn't be there. Filemap changes will thus kick in on the first converted revision, no matter what is changed. This flag should in most cases not make any difference but will make convert significantly slower. Other names has been considered for this feature, such as "resync", "sync", "checkunmodified", "all" or "allfiles", but I found that they were less obvious and required more explanation than "full" and were harder to describe consistently.

Now test that it works with trunk/tags layout, but no branches yet.

Initial svn import

Convert to hg once and also test localtimezone option

NOTE: This doesn't check all time zones -- it merely determines that
the configuration option is taking effect.

An arbitrary (U.S.) time zone is used here.  TZ=US/Hawaii is selected
since it does not use DST (unlike other U.S. time zones) and is always
a fixed difference from UTC.
