Change 782
Initial return of the Alias|Wavefront mods to jam 2.2.
I made a
stab at a configuration system - see the file Jamfile.config.
Most of the mods are now enclosed within #ifdef blocks, which
kind of pollutes the code, but may make it easier to accept
or reject some of these changes. Some of these #ifdefs could
disappear completely if they are accepted into the mainline
This return implements the following extensions:
* header cache
* dynamic command block size, allowing for *large* commands
* slightly improved warnings and errors
* serial output from jam - nice when working with multiple jobs
* an extension to variable modifiers: $(>:/) and $(>:\\)
* ability to ignore header dependencies for a build (jam -p)
* new debug level, -d+10, which outputs the dependency graph
* added no-care support to internal nodes. if they fail, dependents
are built anyway
* time stamps on output
* a few minor output modifications
* a fix for nt batch file names conflicing when more than one jam runs
at a time
Each of the above can be enabled/disabled on the command line. For
example, to turn on the HeaderCache code:
jam -sHeaderCache=1
that is, build jam first, then use that jam to build a new one with the
options you want.
Some of these changes may have been made in the mainline already, my next
step will be to integrate the mainline changes into these ones
This return isn't yet ready for prime-time
