 ## Building

+GNU Make and an `g++` (GNU C++) required. Builds tested in Debian, Cygwin with Mingw64, and GNUWin32.
+In the top-level PSCrypto directory (not the subfolder), run
 
 ```shell
-$ make -j4
+$ make -j4 # build for current system
 ```
 
+This will build the CryptoPP dependency and then the `pscrypto` library, which links to CryptoPP. The pscrypto build artifact will be in pscrypto/ as `libpscrypto.so` or `pscrypto.dll` depending on your platform. Note that the library architecture must match that of the JVM or process you are loading it in to, otherwise you will see loader errors.

+You can also specify the `ARCH` variable manually (as `i686` or `x86_64`) in order to enable multilib building, if available.
