-can cause non-linear history to be flattened when committing into SVN,
-which can lead to merge commits reversing previous commits in SVN.

Formerly, this option controlled how many revisions to pull,

+ Specify how often git repository should be repacked.
++
+The default value is 1000. git-svnimport will do import in chunks of 1000
+revisions, after each chunk git repository will be repacked. To disable

+revisions to import.

-P <path_from_trunk>::
Partial import of the SVN tree.

-to list all files and you can say `git commit -a` (which stands for 'all')
-instead of running `git add` beforehand.

$ git commit -a

A note on commit messages: Though not required, it's a good idea to
begin the commit message with a single short (less than 50 character)
