| 80 |       Boost.Jam (BJam) is a build tool based on FTJam, which in turn is based on |

|---|
| 82 |       contains significant improvements made to facilitate its use in the Boost Build | 
|---|
| 83 |       System, but should be backward compatible with <a href="http://www.perforce.com/jam/jam.html" target="_top">Perforce | 
|---|
| 84 |       Jam</a>. | 
|---|
| 85 |     </p> | 
|---|
| 86 | <p> | 
|---|
| 87 |       This is version 3.1.14 of BJam and is based on version 2.4 of Jam/MR: |

| 102 |         Jam is a make(1) replacement that makes building simple things simple and | 
|---|
| 103 |         building complicated things manageable. | 
|---|
| 104 |       </p> | 
|---|
| 105 | <p> | 
|---|
| 106 |         Jam's language is expressive, making Jamfiles (c.f. Makefiles) compact. | 
|---|
| 107 |       </p> | 
|---|
| 108 | <p> | 
|---|
| 109 |         Jam handles header file dependencies automatically and on-the-fly. | 
|---|
| 110 |       </p> | 
|---|
| 111 | <p> | 
|---|
| 112 |         Jam is very portable: it runs on UNIX, VMS, Mac, and NT. Most Jamfiles themselves | 
|---|
| 113 |         are portable. | 
|---|
| 114 |       </p> | 
|---|
| 115 | <p> | 
|---|
| 116 |         Jam is unintrusive: it is small, it has negligible CPU overhead, and it doesn't | 
|---|
| 117 |         create any of its own funny files (c.f. Odin, nmake, SunOS make). | 
|---|
| 118 |       </p> | 
|---|
| 119 | <p> | 
|---|
| 120 |         Jam can build large projects spread across many directories in one pass, | 
|---|
| 121 |         without recursing, tracking the relationships among all files. Jam can do | 
|---|
| 122 |         this with multiple, concurrent processes. | 
|---|
| 123 |       </p> | 
|---|
| 124 | <p> | 
|---|
| 125 |         Jam isn't under the blinkin GNU copyright, so you can incorporate it into | 
|---|
| 126 |         commercial products. |
