 SAPL is a purely functional, intermediate language and related infrastructure for supporting cross-compilation of lazy functional languages to different target platforms. It currently supports Clean and Haskell/GHC as source languages and provides JavaScript as target platform, however a DART target is under development. SAPL is extensively used in the ITasks project, furthermore various GHC based projects are experimenting with SAPL. Getting startedSo far, no official version of the SAPL compiler infrastructure is released. The current development version can be checked out from https://svn.cs.ru.nl/repos/clean-sapl. Build instructions can be found at SAPL/Build ToolsCompiling Clean or Haskell to JavaScript consists of three easy steps. First, you need to compile the necessary source code modules to the SAPL language. The execution of this step depends on the source language you would like to use. Instructions for Clean and Haskell/GHC can be found at [[]] and [[]], respectively. The second step is to collect and combine, starting with some root expressions, the necessary functions recursively into one SAPL file. Engaging on this linking step helps with reducing the final code size as much as possible. The linking is done using the `sl` command. A simple example for its usage is as follows: $(SL) --expr=Main.main js/$*.sapl
