Subject svn commit: r201819 - /incubator/lucene4c/trunk/src/cmdline/main.c
Date Sun, 26 Jun 2005 09:59:25 GMT
Author: rooneg
Date: Sat Jun 25 20:08:29 2005
New Revision: 201819

URL: http://svn.apache.org/viewcvs?rev=201819&view=rev
Log:
Add a start at an 'lcn index' command, which adds a number of documents
to an index.  So far it only includes the paths for the docs in the index,
but eventually it will be expanded to include the contents as well, which
will be rather more useful ;-)

* src/cmdline/main.c
  (lcn_index_cmd): new command.
  (index_entry): helper function for lcn_index_cmd.
