Hi Overmind,

I am trying to parse multiple files with the structure indicated below. 
I sort of got started, but I hate it if I am going to hit a wall.

I guess I could start by defining a line like this:

string variable   = "([A-Za-z0-9][\\w\\h\\(\\)\\-\\.,/&]*)";
char equal_sign   = '=';
string value      = "(.+)";
string assignment = variable + equal_sign + value;

string line       = assignment + eol;

Any tips and hints are most appreciated and welcome...
