# 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
10+
# .clobber-pre: called before 'clobber' 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.
