# Set of procedures for management of Apache modules


# addModule --
# Given a module:
#     add directives
#     add property pages
#     add association property pages  <--> nodes
#
# Arguments:
#     filename   Filename with the module definition
#     dirDef     Object where to store the directives
#     ppDef      Object where to store the Property pages
#     moduleManager Object where to store which property pages
#                 correspond to which node, etc
#     parser    Apache parser
#     dumper    Apache dumper (to add parsing and dumping procedures)
