Finding the path to a file

Hey,

I have been working on a program that stores
information for each user in a subdirectory of the
directory in which the script is run. So if my script
is in /home/someuser/myprogram, the config files and
such are in /home/someuser/myprogram/config. Now if I
invoke the interpreter from the same directory as the
script is in I can load and save the files because cwd
points to that directory(I used cwd to get the path
and then add /config to it to get to the proper
directory)

My problem is that if I invoke it with a command like
python /home/someuser/myprogram but I am in
/home/someuser, cwd does not point to the scripts
directory but to the directory the interpreter was
invoked from. This means I don't know how to find the
config files other than making them hard coded to a
certain directory. I don't want to hard code them
however so that the program can be contained in one
directory and easily removed and I also don't want to
have to specify where a user installs the program. 

So basically, I want to know how to find the directory
my script is in, even when it is invoked from another
directory. Any help would be greatly appreciated.

Thanks in advance,
Todd A. Johnson
