1Welcome to Cython! 2================= 3 4Cython (http://cython.org) is a language that makes writing C extensions for 5the Python language as easy as Python itself. Cython is based on the 6well-known Pyrex, but supports more cutting edge functionality and 7optimizations. 8 9The Cython language is very close to the Python language, but Cython 10additionally supports calling C functions and declaring C types on variables 11and class attributes. This allows the compiler to generate very efficient C 12code from Cython code. 13 14This makes Cython the ideal language for wrapping external C libraries, and 15for fast C modules that speed up the execution of Python code. 16 17LICENSE: 18 19The original Pyrex program was licensed "free of restrictions" (see 20below).
