Development Version

Some users may wish to run the development version of Clozure CL, which is often called the "trunk".

To get the trunk version of Clozure CL for Darwin/x86, you'd type (where the $ is the shell prompt):

$ svn co http://svn.clozure.com/publicsvn/openmcl/trunk/darwinx86/ccl

To get a version for a different platform, change the darwinx86 to linuxx86, freebsdx86, solarisx86, windows, linuxppc, or linuxarm.

If you choose to run the trunk, please read about tracking the development version.

Documentation

The Clozure CL manual is available as a single web page at ​http://ccl.clozure.com/ccl-documentation.html or as multiple pages at ​http://ccl.clozure.com/manual/. As of Clozure CL 1.2, the DocBook sources for the manual are included with the distribution.
