As first step I implemented the following syntax.
svnadmin lock REPOS PATH USERNAME COMMENT-FILE
I will add the optional TOKEN argument later. I hope I am progressing in
the right direction.
Log
[[[
Fix issue #3942. Add new sub command 'lock' for 'svnadmin'. The
following syntax is implemented in this patch.
svnadmin lock REPOS PATH USERNAME COMMENT-FILE
The command locks the PATH by USERNAME setting comment from
COMMENT-FILE.
The optional TOKEN argument mentioned in issue tracker will be
implemented in another patch.
* subversion/svnadmin/main.c
(svn_opt_subcommand_t): New sub command.
(svn_opt_subcommand_desc2_t): Add description.
(subcommand_lock): Implement it.
* subversion/tests/cmdline/svnadmin_tests.py
(lock): New test for 'lock' sub command.
(test_list): Add new test.
Patch by: Noorul Islam K M <noorul{_AT_}collab.net>

Thanks and Regards
