I'm using
python-magic
and I've installed it using
sudo apt-get remove libmagic-dev
In order to cite it properly, when i tried to find the authors online, i realized there are multiple libmagic libraries, e.g.
What is the source of the libmagic-dev found in the ubuntu apt-get repo?
python-magic depends on libmagic1
$ apt-cache show python-magic | grep ^Depend
Depends: python (>= 2.7.1-0ubuntu2), python (<< 2.8), libmagic1 (= 5.11-2ubuntu4)
According to package information, libmagic1 is from http://www.darwinsys.com/file/
$ apt-cache show libmagic1 | grep ^Homepage
