Indeed it is, APT uses a config file that is basically identical to that,
the parser is about 300 lines of C++. It also integerates with the custom
command line parser to create a single in-memory database of key-value
pairs that represent the entire configuration space for the process. The
only difference is that I stole the syntax from the ISC tools (bind,
dhcp, etc)
It is quite simple and extendable, there is even a C program to interface
with shell scripts called apt-config, ie:
set -e
RES=`apt-config shell CLEAN DSelect::Clean OPTS DSelect::Options \
DPKG Dir::Bin::dpkg APTGET Dir::Bin::apt-get`
eval $RES
Works for me :>
