samer@6: 
samer@6: This  module  make  ClioPatria  more    suitable   for  development.  In
samer@6: particular, it implements the following methods:
samer@6: 
samer@6:     * Load library(http/http_error), which causes uncaught Prolog
samer@6:     exceptions to produce an HTML page holding a stack-trace.
samer@6:     * Load library(semweb/rdf_portray), which prints RDF resources
samer@6:     in a more compact way.
samer@6:     * Load library(semweb/rdf_db) into the module =user=.  This allows
samer@6:     usage of rdf/3, rdf_load/1, etc. from the toplevel without
samer@6:     specifying the module.
samer@6:     * Use debug/1 on the _topic_ http(request), which causes the
samer@6:     toplevel to print basic information on the HTTP requests processed.
samer@6:     Using copy/paste of the HTTP path, one can assemble a command that
samer@6:     edits the implementation of a page.
samer@6: 
samer@6:         ==
samer@6:         ?- edit('/http/path/to/handler').
samer@6:         ==
samer@6:     * Define tmon/0 that brings up a graphical tool showing thread
samer@6:     activity.
