how to install changelog?

[anonymous]

Hi,

I'm new to trac... I would like to install the changelog plugin.

I placed the files into my plugins folder on:

root@tracsrv1:/usr/share/trac/plugins/tracchangelog# ls -al
insgesamt 16
drwxr-xr-x 2 root root 4096 2007-10-19 21:05 .
drwxr-xr-x 4 root root 4096 2007-10-19 21:05 ..
-rw-r--r-- 1 root root   51 2007-10-19 21:05 __init__.py
-rw-r--r-- 1 root root 1622 2007-10-19 21:05 tracchangelog.py

then i've edited the trac conf file, by adding the following line to the components section:

tracchangelog.* = enabled

finally i've restarted apache...

but nothing happend, when i've entered the following line into the wiki...

[[ChangeLog(/some/file/in/svn, 5)]]

what's wrong here?

Thanks in advance for any reply
