[xemacs-hg @ 2002-09-10 15:27:02 by james] Enable unloading of dynamic modules. Create the first two internal XEmacs modules: LDAP and postgreSQL. Update the sample directory to contain a sample internal XEmacs module and a sample external XEmacs module. Improve support for autoloading modules. Make internal module code compile into the XEmacs binary if XEmacs is configured without module support. Make the internal module directories self-contained so that they can be distributed separately from XEmacs.
