"""Routines to read ISC config-alike configuration files.
There are a few changes from the real ISC Style:
- comments start with a # and last until the end of the line
- IP addresses are not supported, you will have to use strings for those
An example of a file in this format::
# Example configuration
datasource1 {
server "server1.your.domain";
username "client";
password "secret";
};
datasource2 {
server "server2.your.domain";
username "client";
password "secret";
};
tables {
"users";
"groups";
}
