-- initialise Lua bindings for PLplot examples.
--[[
The Lua 5.0 stanza below was temporarily tested for Lua 5.2 by
changing "Lua 5.0" to Lua 5.2 and converting all loadlib calls to
package.loadlib. That test was a success (as was a test for the
non-Lua-5.0 stanza below when these temporary changes were removed)
when WRITEABLE_TARGET was non-null (which occurs when the user
uses the -DUSE_WRITEABLE_TARGET_TEST_PREFIX=ON option). So
likely a real Lua 5.0 environment will work, but that has not
been explicitly tested.
