Hello:

I like scons model for software development, it is simple and quite powerful. 
However, I stumbled when I tried  to write an SConstruct file that searches for 
"C" and "Fortran" compilers in an order prescribed by me.  For example: assume 
that  I have "icc", "gcc" and "gcc-mp-4.6" on a mac (all paths to the 
executables are in the scons path, so no problem finding each of these 3 
tools).  

Then I'd like to have scons to search for tools in the following order: check 
for "icc", if not found, then check for "gcc-mp-4.6" and if not found then fall 
back to "gcc" (or just go through the rest of the compilers that are default in 
the "tool specifications" as indicated on the scons man page). 

Similar applies to Fortran compilers (or any other tools). I think it will be 
good to either include example in the man pages accomplishing the above 
"ordered search task" (if such example can be provided) or include this in 
future versions of scons (if it appeals to you). 

Thank you for your consideration. 

regards, 
--Ludmil
