DESCRIPTION="Software development platform including components for 3D surface and solid modeling, visualization, data exchange and rapid application development."
HOMEPAGE="http://www.opencascade.org"
SRC_URI="ftp://ftp.freebsd.org/pub/FreeBSD/ports/local-distfiles/thierry/${P}.tar.bz2

# The source code here is NOT in the same form than the one distributed on opencascade.org
# The source available on 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 -DOS_NAME=Linux -Dtemp.dir=/some/big/dir/tmp run'
# and removing 'by hand' all the existing Linux binaries.
# The source code extracted using this method is available (for the time being) 
# on the FreeBSD ftp server.
# An other possibility is to download the Salome binary for linux (500Mb...)
# and to extract the source code for OpenCascade from there.
#
# In any case, none of these solutions are really satisfactory. A better method should
# be found
