| # 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. |
