Welcome to Cython!
=================
-Cython (http://www.cython.org) is based on Pyrex, but supports more
-cutting edge functionality and optimizations.
+Cython (http://cython.org) is a language that makes writing C extensions for
+the Python language as easy as Python itself. Cython is based on the
+well-known Pyrex, but supports more cutting edge functionality and
+optimizations.
+
+The Cython language is very close to the Python language, but Cython
+additionally supports calling C functions and declaring C types on variables
+and class attributes. This allows the compiler to generate very efficient C
+code from Cython code.
+
+This makes Cython the ideal language for wrapping external C libraries, and
+for fast C modules that speed up the execution of Python code.

--------------------------
-There are TWO mercurial (hg) repositories included with Cython:
-
- * Various project files, documentation, etc. (in the top level directory)
- * The main codebase itself (in Cython/)
-
-We keep these separate for easier merging with the Pyrex project.
-
-To see the change history for Cython code itself, go to the Cython
-directory and type
-
- $ hg log
+Note that Cython used to ship the full version control repository in its source
+distribution, but no longer does so due to space constraints. To get the
+full source history, make sure you have git installed, then step into the
+base directory of the Cython source distribution and type
-This requires that you have installed Mercurial.
+ make repo
