-+
+# new()         : A new FeatureTool object
-+
+# name()        : get/set the tools name
-+
+# version()     : get set the tool version
-+
+# url()         : get set the tool url
-+
+# features()    : return a list of features defined (ordered in relation to
-+
+#                       their first definition)
-+
+# listtype(type) : return a list of all features of the specified type
-+
+# addfeature(name,@value) : add value(s) to the named feature
-+
+# setfeature(name,@value) : set value(s) for the named feature
-+
+# getfeature(name) : return a list of elements belonging to the named feature
-+
+#                       (with embedded dependencies)
-+
+# type(name[,type]) : get/set the type associated with a feature
-+
+# addrequirement() : add a requirement at the current parse position
-+
+# dependencies()   : return a list of dependency objects
-+
+# store(location)   : Save object to given file
-+
+# restore(location) : Restore object from specified file
-+
+# reset()           : Clean out all the features
-+
+# equals(toolobj)       : return 1 if the tools correspond in url version etc.
