+# Criterion: robust, reliable performance measurement
+This package provides the Criterion module, a Haskell library for
+measuring and analysing the performance of Haskell programs.
+To get started, read the documentation for the Criterion.Main module,
+and take a look at the programs in the examples directory.
+# Building and installing
+To build and install criterion, just run
+ cabal install criterion
+On Mac OS X, the Chart library that criterion uses is not available,
+so you'll have to build without it.
+ cabal install criterion -f-chart
+This will lose you the ability to generate charts, but you'll still be
+able to generate CSV files and import them into your favourite
+spreadsheet, or gnuplot, or whatnot.
+Please report bugs via the
+[bitbucket issue tracker](http://bitbucket.org/bos/criterion).
+Master [Mercurial repository](http://bitbucket.org/bos/criterion):
+* `hg clone http://bitbucket.org/bos/criterion`
+There's also a [git mirror](http://github.com/bos/criterion):
+* `git clone git://github.com/bos/criterion.git`
+(You can create and contribute changes using either Mercurial or git.)
