Purpose

Import classic bookmarks (created using up to REVEN 2.4) from ".rbm" files to the "server-side" bookmarks system (from REVEN 2.5+).

How to use

usage: import_bookmarks.py [-h] [--host HOST] [-p PORT] [-f FILENAME]
                           [--prepend-symbol]

optional arguments:
  -h, --help            show this help message and exit
  --host HOST           Reven host, as a string (default: "localhost")
  -p PORT, --port PORT  Reven port, as an int (default: 13370)
  -f FILENAME, --filename FILENAME
                        Path to the classic bookmark file (*.rbm).
  --prepend-symbol      If set, prepend the OSSI symbol as stored in the
                        classic symbol file to the description of the bookmark
