No solo puede hacer que la salida del compilador sea más corta, puede colorearla y agregar un indicador detallado. La salida será algo como esto:

Así es como (tema de color robado del SCons Wiki):
import os,sys
colors = {}
colors['cyan'] = '\033[96m'
colors['purple'] = '\033[95m'
colors['blue'] = '\033[94m'
colors['green'] = '\033[92m'
colors['yellow'] = '\033[93m'
colors['red'] = '\033[91m'
colors['end'] = '\033[0m'
#If the output is not a terminal, remove the colors
if not sys.stdout.isatty():
for key, value in colors.iteritems():
colors[key] = ''
compile_source_message = '%s\nCompiling %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
compile_shared_source_message = '%s\nCompiling shared %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
link_program_message = '%s\nLinking Program %s==> %s$TARGET%s' % \
(colors['red'], colors['purple'], colors['yellow'], colors['end'])
link_library_message = '%s\nLinking Static Library %s==> %s$TARGET%s' % \

(colors['red'], colors['purple'], colors['yellow'], colors['end'])
java_compile_source_message = '%s\nCompiling %s==> %s$SOURCE%s' % \
(colors['blue'], colors['purple'], colors['yellow'], colors['end'])
java_library_message = '%s\nCreating Java Archive %s==> %s$TARGET%s' % \

env = Environment()
AddOption("--verbose",action="store_true", dest="verbose_flag",default=False,help="verbose output")
if not GetOption("verbose_flag"):
env["CXXCOMSTR"] = compile_source_message,

compilar con "scons --verbose" para ver el gcc voluminosos normales salida.

¿Algún ejemplo real del uso de archivos de especificaciones? – florin
