# Makefile for building libLauncher.so
#
# To build libLauncher.so requires :-
#     JAVA_HOME environment variable
#     cc (Solaris) or gcc (Linux) on PATH
#
# The library is created in a architecture specific directory :-
#
#     lib/solaris-sparc/libLauncher.so  (Solaris/SPARC)
#     lib/solaris-i586/libLauncher.so   (Solaris/x86)
#     lib/linux-i586/libLauncher.so (Linux/x86)
