Installation
--------------------
# Install libgcrypt first, e.g. via `brew install libgcrypt` on OS X or libgcrypt-dev on Linux
# Generate the final build scripts
./autogen.sh
# Build the CLI and library
./configure && make

Troubleshooting
--------------------
If libgcrypt isn't found after install, set AM_PATH_LIBGCRYPT env var to libgcrypt path 
prior to running autogen.sh. For example, on OS X with ver 1.7.6:

export AM_PATH_LIBGCRYPT="/usr/local/Cellar/libgcrypt/1.7.6/lib"
