 WRITING THE GENCODE SCRIPT
 --------------------------
+There are two gencode scripts: gencode-local and gencode-remote.
+The output of gencode-local is executed locally, whereas
+the output of gencode-remote is executed on the target.
+
 The gencode script can make use of the parameters, the global explorers
 and the type specific explorers. The output (stdout) of this script is
 saved by cdist and will be executed on the target.
