"""Provides support for building through make or ant make using the GPS
   Build Manager.

   This script defines the following new project attributes in the "make"
   package of a .gpr file. They can be edited graphically through
   the project properties editor.
       "make.makefile": name of the Makefile to use. This can be an absolute
                    name, or a name relative to the directory containing the
                    root project file (ie the one loaded in GPS). This
                    attribute is optional. If unspecified, GPS will look for
                    either "Makefile" or "makefile" in the directory
                    containing the root project.

   This script defines the following new project attributes in the "ant"
   package of a .gpr file:
       "ant.antfile": name of the Antfile to use. This can be an absolute
                    name, or a name relative to the directory containing the
                    root project file (ie the one loaded in GPS). This
                    attribute is optional. If unspecified, GPS will look for
                    "build.xml" in the directory containing the root project.

   GPS will systematically compile the application by passing the scenario
   variables (see the menu /Tools/Views/Scenario). For instance, this
   will result in calling
       make -f Makefile VARIABLE1=VALUE target
   or
       ant -buildfile build.xml -DVARIABLE1=VALUE target

   These scenario variables are defined in the project file, and should have
   the same name as in the Makefile or the AntFile.

   By default, the name in the menu will be the name of the targets found in
   the build file.
   As a special case, when the comment is "IGNORE", as in:

      target: dependency1 dependency2 # IGNORE

   then that target is not displayed in the menu

   A similar behavior is applied for build.xml files for ant, where the
   "description" attribute of the <target> node is taken into account.

   When you select one of the new menus, GPS will run ant or make, and parse
   error messages to display them in the locations window as usual.
