+# NOTES
+# The source code here is not in the same form than the one distributed on www.opencascade.org
+# The source available on www.opencascade.org requires a Java installation procedure that does not
+# always work on Gentoo. The source code can however be extracted 'by hand' using
+# 'java -cp ./Linux/setup.jar'
+# and removing 'by hand' all the existing Linux binaries. The source code extracted using this
+# method is currently available on the FreeBSD ftp server.
+# It could be possible to download the Salome binary for linux (500Mb...) and to extract the source from there.
