+ at subsection Environment variables
+The clFFT library looks for the definition of 2 environment varibles. One is CLFFT_CACHE_PATH. If this
+variable is defined, then the library caches OpenCL binaries. This will enable a subsequent application run
+of the same type of transforms to avoid going through the expensive compile step. Instead, the stored
+binaries are loaded and executed. The CLFFT_CACHE_PATH must point to a folder location where the
+library can store binaries. The other environment variable is CLFFT_REQUEST_LIB_NOMEMALLOC. This
+variable when defined asks the library to do all computations in-place and avoid allocating extra
+device memory whenever possible. This feature is experimental and currently works only for certain types
+of transforms, and where the input can be decomposed into square matrices by the library. Currently it
+works for 1D complex transforms of size of even powers of 2,3,5 and 7.

 A plan is the collection of (almost) all the parameters needed to specify an FFT computation.
