45# Examples:
46# These two commands are equivalent. The '-u' option tells scons to
47# search up the directory tree for this SConstruct file.
48# % cd <path-to-src>/m5 ; scons build/ALPHA_FS/m5.debug
49# % cd <path-to-src>/m5/build/ALPHA_FS; scons -u m5.debug
50# These two commands are equivalent and demonstrate building in a
51# directory outside of the source tree. The '-C' option tells scons
52# to chdir to the specified directory to find this SConstruct file.
53# % cd <path-to-src>/m5 ; scons /local/foo/build/ALPHA_FS/m5.debug
