well, I'll post the basics of one of my mt.cfg file below. The path to perl is correct as default so you don't need to edit that. And the other stuff is pretty self explnitory if you want to change things around.
Movable Type configuration file [mt.cfg]
This configuration file holds system-wide configuration
settings that apply to all of the blogs in your Movable
Movable Type uses the CGIPath setting to construct links back to
CGI scripts; for example, the MT tag <$MTCGIPath$> is substituted
with the value of the CGIPath setting. You will need to change this
value when you first install MT; instructions for doing so are in
the Installation Instructions, in INSTALLING THE MOVABLE TYPE
APPLICATION CODE, Step 3.
The filesystem path to the 'db' directory, where your MT database
files are stored. You will probably need to change this when you
first install MT; instructions for doing so are in the Installation
Instructions, in INSTALLING THE MOVABLE TYPE APPLICATION CODE, Step 8.
Consider using the MySQL configuration, below.
The following options are commented out: to uncomment an
option, remove the '#' at the beginning of the line.
First, however, make sure that you understand the purpose
of the configuration setting.
Configuration for MySQL databases. Add the name of your database
and the username that you have for logging in to that database
below. The password needs to go in the file mt-db-pass.cgi.
ThrottleSeconds is the minimum number of seconds between comments
from a single IP address. Setting this to 0 will turn off the
throttling feature, which may make you vulnerable to
comment-flooding. The default is 20.
MT needs to have an email address, from which it can send notification
emails. This defaults to your author address, but some spam filters
will reject emails that are From: and To: the same address. If you
have another address you can use it here.
----- Now there's a bunch of lines that are all commented out untill this part-----
When creating files and directories, Movable Type uses umask settings to
control the permissions set on the files. The default settings for file
creation (HTMLUmask, DBUmask, and UploadUmask) are 0111; for directory
creation (DirUmask), the default is 0000. You should not change these
settings unless you are running MT under cgiwrap or suexec, or some other
scenario where the MT application runs as you; in addition, you should not
change these settings unless you know what they mean, and what they do.
---- And everything else in the file is default. ----
Should be pretty simple. Just read the lines where they explain what each variable is, and how to set it. Any line that starts with a # will be ignored by the program, so to "uncomment" something you just remove the #.
Hope this is helpful.
