# IceCream distributed compiling support
#
-# We need to create a tar.bz2 of our toolchain and set
-# ICECC_VERSION, ICECC_CXX and ICEC_CC
+# Stages directories with symlinks from gcc/g++ to icecc, for both
+# native and cross compilers. Depending on each configure or compile,
+# the directories are added at the head of the PATH list and ICECC_CXX
+# and ICEC_CC are set.
#
+# For the cross compiler, creates a tar.gz of our toolchain and sets
+# ICECC_VERSION accordingly.
+#
+#The class now handles all 3 different compile 'stages' (i.e native ,cross-kernel and target) creating the
+#necessary enviroment tar.gz file to be used by the remote machines
+#
+#If ICECC_PATH is not set in local.conf then the class will try to locate it using 'which'
+#but nothing is sure ;)
+#
+#If ICECC_ENV_EXEC is set in local.conf should point to the icecc-create-env script provided by the user
+#or the default one provided by icecc-create-env.bb will be used
+#(NOTE that this is a modified version of the script need it and *not the one that comes with icecc*
+#
+#User can specify if specific packages or packages belonging to class should not use icecc to distribute
+#compile jobs to remote machines, but handled localy, by defining ICECC_USER_CLASS_BL and ICECC_PACKAGE_BL
+#with the appropriate values in local.conf
