Makefile

#
#  There exist several targets which are by default empty and which can be 
#  used for execution of your targets. These targets are usually executed 
#  before and after some main targets. They are: 
#
#     .build-pre:              called before 'build' target
#     .build-post:             called after 'build' target
#     .clean-pre:              called before 'clean' target
#     .clean-post:             called after 'clean' target
#     .clobber-pre:            called before 'clobber' target
#     .clobber-post:           called after 'clobber' target
#     .all-pre:                called before 'all' target
#     .all-post:               called after 'all' target
#     .help-pre:                called before 'help' target
#     .help-post:               called after 'help' target
#
#  Targets beginning with '.' are not intended to be called on their own.
#
#  Main targets can be executed directly, and they are:
#  
#     build                    build a specific configuration
#     clean                    remove built files from a configuration
#     clobber                  remove all built files
#     all                      build all configurations
#     help                     print help mesage
#  
#  Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
#  .help-impl are implemented in nbproject/makefile-impl.mk.
