This repo is an adoption of squashfs-tools for Mac OS X. It was done to be able to unpack Mikrotik's *.npk files, which contain a SquashFS stream inside.
Some additional libraries may be required for building, like xz, lzo2. They can be installed with MacPorts.
Compilation is performed by simply running make command. Installation is performed with sudo make install.
The original squashfs-tools is taken from git://git.kernel.org/pub/scm/fs/squashfs/squashfs-tools.git.
