   4/** <module> Set options for development
   5
   6This  module  make  ClioPatria  more    suitable   for  development.  In
   7particular, it implements the following methods:
   8
   9    * Load library(http/http_error), which causes uncaught Prolog
  10    exceptions to produce an HTML page holding a stack-trace.
  11    * Load library(semweb/rdf_portray), which prints RDF resources
  12    in a more compact way.
  13    * Load library(semweb/rdf_db) into the module =user=.  This allows
  14    usage of rdf/3, rdf_load/1, etc. from the toplevel without
  15    specifying the module.
  16    * Use debug/1 on the _topic_ http(request), which causes the
  17    toplevel to print basic information on the HTTP requests processed.
  18    Using copy/paste of the HTTP path, one can assemble a command that
  19    edits the implementation of a page.
  20
  21        ==
  22        ?- edit('/http/path/to/handler').
  23        ==
  24    * Define tmon/0 that brings up a graphical tool showing thread
  25    activity.
