2   -# There exist several targets which are by default empty and which can be
3   -# used for execution of your targets. These targets are usually executed
4   -# before and after some main targets. They are:
5   -#
6   -# .build-pre: called before 'build' target
7   -# .build-post: called after 'build' target
8   -# .clean-pre: called before 'clean' target
9   -# .clean-post: called after 'clean' target

11   -# .clobber-post: called after 'clobber' target
12   -# .all-pre: called before 'all' target
13   -# .all-post: called after 'all' target
14   -# .help-pre: called before 'help' target
15   -# .help-post: called after 'help' target
16   -#
17   -# Targets beginning with '.' are not intended to be called on their own.
18   -#
19   -# Main targets can be executed directly, and they are:
20   -#
21   -# build build a specific configuration
22   -# clean remove built files from a configuration
23   -# clobber remove all built files
24   -# all build all configurations
25   -# help print help mesage
26   -#
27   -# Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
28   -# .help-impl are implemented in nbproject/makefile-impl.mk.
