[Nek5000-users] new build system

[nek5000-users at lists.mcs.anl.gov]

Hello all,

No major complaints with the compile procedure.  For one thing, I must
say I am very impressed by the speed at which the code compiles!  Very
surprising considering the capabilities of NEK.  

One suggestion would be to have a way to build testing and production
versions.  The testing version would be compiled with all the debug
switches on (i.e. check bounds etc.) and would be used when users are
making changes in the *.usr file and debugging.  The production version
would use compile switches that the development team finds to be best
for speed on particular platforms.

Cheers,
Frank
