Recently when i tried to install something with Sourcery i was asked to enter options. And there were give this 2 statements (which i presume they were the default: foo=yes bar=no. Now, i'm absolutely clueless about them (normally when i did not install packages but had to install a tarball by ./configure make sudo make install i trusted in the README (in case there were hints to options etc.).
Is there somewhere a link to a documentation where i could read something about (please not hundreds of pages online ...

)?
TIA
