+option, but on some not very scientific tests it averaged about twenty
+revisions per second, so a medium-sized project should not take more

+After the (initial) import is done, the CVS archive's current head
+revision will be checked out -- thus, you can start adding your own
+changes right away.
+The import is incremental, i.e. if you call it again next month it'll
+fetch any CVS updates that have been happening in the meantime. The
+cut-off is date-based, so don't change the branches that were imported
+from CVS.
+You can merge those updates (or, in fact, a different CVS branch) into
+your main branch:
+ cg-merge <branch>
+The HEAD revision from CVS is named "origin", not "HEAD", because git
+already uses "HEAD". (If you don't like 'origin', use cvsimport's
+'-o' option to change it.)

+Imports a CVS repository into git. It will either create a new
+repository, or incrementally import into an existing one.
+Splitting the CVS log into patch sets is done by 'cvsps'.
+At least version 2.1 is required.
+-d <CVSROOT>::
+ The root of the CVS archive. May be local (a simple path) or remote;
+ currently, only the :local:, :ext: and :pserver: access methods
+ are supported.
+-o <branch-for-HEAD>::
+ The 'HEAD' branch from CVS is imported to the 'origin' branch within
+ the git repository, as 'HEAD' already has a special meaning for git.
+ Use this option if you want to import into a different branch.
+ Use '-o master' for continuing an import that was initially done by
+ the old cvs2git tool.
+-p <options-for-cvsps>::
+ Additional options for cvsps.
+ The options '-x' and '-A' are implicit and should not be used here.
+ If you need to pass multiple options, separate them with a comma.
+ Verbosity: let 'cvsimport' report what it is doing.
+ The CVS module you want to import. Relative to <CVSROOT>.
+ Print a short usage message and exit.
+If '-v' is specified, the script reports what it is doing.
+Otherwise, success is indicated the Unix way, i.e. by simply exiting with
+a zero exit status.
