[Scons-users] Hierarchical builds not possible (TAR/RPM packaging)

[Werner Reisberger]

Sorry, I used the wrong quotation for the user guide. The statement from 
the user guide which is right in my point of view is:

>> Second, unlike standard recursive use of Make, SCons stays in the 
>> top-level directory (where the SConstruct
>> file lives) and issues commands that use the path names from the 
>> top-level directory to the target and
>> source files within the hierarchy.

The wrong statement from the man page is:

>> By default, scons changes its working directory to the directory in 
>> which each subsidiary SConscript file lives.
