Update of /cvsroot/spambayes/spambayes/contrib
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv11026/contrib
Added Files:
showclues.py
Log Message:
A little script that outputs to stdout a 'show clues' report like the one that
Outlook
creates, with the clues, tokens and message stream.
--- NEW FILE: showclues.py ---
#!/usr/bin/env python
"""Usage: showclues.py [options] [filenames]
Options can one or more of:
-h
show usage and exit
-d DBFILE
use database in DBFILE
-p PICKLEFILE
use pickle (instead of database) in PICKLEFILE
-m
markup output with HTML
-o section:option:value
set [section, option] in the options database to value
If no filenames are given on the command line, standard input will be
processed as a single message. If one or more filenames are given on the
command line, each will be processed according to the following rules:
* If the filename is '-', standard input will be processed as a single
message (may only be usefully given once).
* If the filename starts with '+' it will be processed as an MH folder.
* If the filename is a directory and it contains a subdirectory named
'cur', it will be processed as a Maildir.
* If the filename is a directory and it contains a subdirectory named
'Mail', it will be processed as an MH Mailbox.
* If the filename is a directory and not a Maildir nor an MH Mailbox, it
will be processed as a Mailbox directory consisting of just .txt and
.lorien files.
* Otherwise, the filename is treated as a Unix-style mailbox (messages
begin on a line starting with 'From ').
