# oe_jarinstall foo-1.3.jar foo.jar
# Installs foo-1.3.jar and creates symlink foo.jar.
#
# oe_jarinstall -s foo-1.3.jar foo.jar
# Installs foo-1.3.jar to staging and creates symlink foo.jar.
#
# oe_jarinstall -r foo-1.3.jar foo_1_3.jar foo.jar
# Installs foo_1_3.jar as foo-1.3.jar and creates a symlink to this.
