Written 2005-09-18 (by GD)
Updated 2005-09-21 15:45 GMT+1 (by GD)
This script is used to replace the existing cfg-update solution
wrapper solution with the purpouse of avoiding unnecessary
waits/delays during emerge operations
Updated 2005-12-31 03:08 GMT+2 (by S. van Boven)
Removed "columns" from bl_fword array because this flag is used
only in combination with --pretend, which is blocked already.
Tested if this script could start the emerge command, but it
turns out that it strips color from the emerge output when it
is started with passthru(). So I made the wrapperscript start
the emerge when this script is done...
Slightly modified the output in case a blacklisted flag is found.
