# Change User Description Committed
#2 1229 Craig Mcpheeters Modified the Jamfile to use the header cache if the feature is on
A couple minor fixes, in cache_name() and hcache_init()
hcache_init().  If the cache is bad, unlink the file.  Avoid use of
   stderr, have all output go to stdout
hcache(), re-organized the do/do-not use logic to avoid duplicated code
#1 1226 Craig Mcpheeters Created a branch which will be used to integrate changes from
   Matt Armstrong's copy of Jam.
//guest/craig_mcpheeters/jam/src/Jamfile
#4 1023 Craig Mcpheeters Integration from //guest/craig_mcpheeters/work/jam/src/...
This return incorporates all of the Alias|Wavefront extensions to
  Jam, into an area which is a proper branch of the Jam mainline.
  An integration of these files into the Jam mainline will show all
  of the differences.
There are several extensions to Jam in this return.  Look at the
  new file Jamfile.config for an explanation of the extensions, and
  how to compile them into your own copy of Jam.  If you want to
  build a copy of Jam with all of the extensions, do this:
    jam -sAllOptions=1
  Read the config file for more info.
The extensions range from minor output tweaks and simple fixes to
  more major things like a header cache, serialization of output from
  multiple jobs, dynamic command block sizing
These are all offered without warranty, etc.
