This script assume that you want to sync your C<trunk> (or any other |
410 |
|
directory for that matter) directory with CVS, not root of your subversion. |
411 |
|
This might be considered bug, but since common practise is to have |
412 |
|
directories C<trunk> and C<branches> in svn and source code in them, it's |
413 |
|
not serious limitation. |

=item r18 |
442 |
|
|
443 |
|
Support for importing your svn into empty CVS repository (it will first |
444 |
|
create module and than dump all revisions). |
445 |
|
Group commit operations to save round-trips to CVS server. |
446 |
|
Documentation improvements and other small fixes. |
447 |
|
|
448 |
|
=item r20 |
449 |
|
|
450 |
|
Fixed path deduction (overlap between Subversion reporistory and CVS checkout). |
451 |
|
|
452 |
|
=item r21 |
453 |
|
|
454 |
|
Use C<update -d> instead of checkout after import. |
455 |
|
Added fixes by Paul Egan <paulegan@mail.com> for XMLin and fixing working |
456 |
|
directory. |
457 |
|
|
458 |
|
=item r22 |
459 |
|
|
460 |
|
Rewritten import from revision 0 to empty repository, better importing |
461 |
|
of deep directory structures, initial support for recovery from partial |
462 |
|
commit. |
