Greg Ward | c3a43b4 | 2000-06-24 18:10:48 +0000 | [diff] [blame] | 26 | The basic idea behind a compiler abstraction class is that each |
| 27 | instance can be used for all the compile/link steps in building a |
| 28 | single project. Thus, attributes common to all of those compile and |
| 29 | link steps -- include directories, macros to define, libraries to link |
| 30 | against, etc. -- are attributes of the compiler instance. To allow for |
| 31 | variability in how individual files are treated, most of those |
| 32 | attributes may be varied on a per-compilation or per-link basis. |
