Updated my netbook

Tags General 

Took some effort to get everything installed the way I want, but it is operational again:

I also my ConfigFile script again.

What this does link config files from I keep in a directory (that is a git repository) to the right location.

It will created the needed directories and link the files into the right place.

it will look for subdirectories read the config file, based on the info in there it will link the files.
Example:<pre lang=”ini” line=1>l:vimrc:~/.vimrc l:vimrc:~/.gvimrc ld:vimdir:~/.vim </pre>

Syntax is very simple:

l:file1:file2

means link file2 to file1

ld:dir1:dir2

is link dir2 to dir1
