C port of the Curl library

Don't forget to grab submodules! use git submodule update --init --recursive when cloning, and git submodule update --recursive when pulling from this repository.

CMake is a build dependency. If you are testing, you must also
install CUnit (BCUnit).

mkdir build && cd build && cmake .. && cmake --build . && cd ..

You may build using mingw or cygwin, but if you build with Visual C++, it is highly recommended that you also install the LLVM compiler, and Microsoft's Build Tools.

mkdir build
cd build
cmake -G "Visual Studio 14 2015" -A x64 -T LLVM-vs2014 ..
cmake --build . --config Release
cd ..

In Windows, the libraries would be located in the build\Release directory.

There are two included command-line programs, ccurl-cli, and ccurl-digest. Usage is as follows:

% ccurl-digest $(ccurl-cli <MinWeightMagnitude> <TransactionTrytes>)

where <MinWeightMagnitude> is replaced with, for example, 18, and <TransactionTrytes> is replaced with your 2673-length transaction.

If using GPU acceleration, you may tune the loop length with ccurl_pow_set_loop_count(my_loop_count); with the library, or setting an environment variable to, for example, CCURL_LOOP_COUNT=64, when using ccurl-cli.
