# Scilab can be installed/used in different ways :
# * ./configure; make install
#    => will install Scilab into /usr/local/ and split files to
#    /usr/local/bin, /usr/local/share/scilab/, /usr/local/lib/scilab/,
#    /usr/local/include/scilab/
# * ./configure --prefix=/my/dir/; make install
#    => will install Scilab into /my/dir/ and split files to
#    /my/dir/bin/, /my/dir/share/scilab/, /my/dir/lib/scilab/
#    /my/dir/include/scilab/
#    Scilab official binary uses this arch
# * ./configure; make install prefix=$(DESTDIR)/usr \
#                   bindir=$(DESTDIR)/usr/bin \
#                   datadir=$(DESTDIR)/usr/share/scilab ...
#    Solution used mainly by Linux packagers
#
## First, this script will look for scilab-bin in :
# * If specified, in the $SCI variable
# * Into the scilab/bin/ directory
# * Into the scilab/ directory (if the user is using a source version and
# scilab has been compiled in this directory)
# * if this file is a symlink to the real one. We browse symlink(s) until we
# find the real "scilab" script file and consider that it is the right
# directory
# * That is all. Don't hesitate to contact us if you see one missing.

#
# Scilab is looking for Java in various places with different ways :
# * if JAVA_HOME is specificed, use it
# * Check in 'standard' places we know Java could be installed
# if some are missing, please contact us
# * look in the PATH if there is a java binary
# if it is the case, resolve the symlink and set the JAVA_HOME from it
#
# Once we have JAVA_HOME, we check that native libraries (libjava.so and
# 2 others) are available
