Building

Copy config.mk.template to config.mk, make changes as required, and then run make. If your make is not GNU make (e.g. on BSD variants), you need to call gmake instead.

To build under windows, you will need to build libgpgerror, and libgcrypt. You may need libiconv when not building on Linux. Fairly recent versions (~1.8.0) are required of the libraries in order to support AES-XTS operations. I recommend using MinGW.
