#
#   Boost Build wxFormBuilder generator tool module.
#
#   wxFormBuilder is a GUI designer tool for the wxWidgets library. It can then
# generate C++ sources modeling the designed GUI using the wxWidgets library
# APIs.
#
#   This module defines a wxFormBuilder project file type and rules needed to
# generate C++ source files from those projects. With it you can simply list
# wxFormBuilder projects as sources for some target and Boost Build will
# automatically convert them to C++ sources and process from there.
#
#   The wxFormBuilder executable location may be provided as a parameter when
# configuring this toolset. Otherwise the default wxFormBuilder.exe executable
# name is used located in the folder pointed to by the WXFORMBUILDER environment
# variable.
#
#   Current limitations:
#
#   * Works only on Windows.
#   * Works only when run via Boost Jam using the native Windows cmd.exe command
#     interpreter, i.e. the default native Windows Boost Jam build.
#   * Used wxFormBuilder projects need to have their output file names defined
#     consistently with target names assumed by this build script. This means
#     that their target names must use the prefix 'wxFormBuilderGenerated_' and
#     have no output folder defined where the base name is equal to the .fpb
#     project file's name.

#
# Implementation note:
#
#   Avoiding the limitation on the generated target file names can be done but
# would require depending on external tools to copy the wxFormBuilder project to
# a temp location and then modify it in-place to set its target file names. On
# the other hand wxFormBuilder is expected to add command-line options for
# choosing the target file names from the command line which will allow us to
# remove this limitation in a much cleaner way.
#                                                    (23.08.2008.) (Jurko)

#
# Implementation notes:
#
#   wxFormBuilder generated CPP and H files need to be moved to the location
# where the Boost Build target system expects them so that the generated CPP
# file can be included into the compile process and that the clean rule
# successfully deletes both CPP and H files. We expect wxFormBuilder to generate
# files in the same location where the provided WX_FORM_BUILDER_PROJECT file is
# located.
