Other than 'grep'ing dmesg, is there a way to know the current cpu such as =
a=20
struct with the machine's cpu and cpu feature (kinda like a time_t struct)?

Portability is not really an issue (though I would be nice if it could run =
on=20
BSD/linux systems).

=46or example, on one of my systems (from dmesg):
CPU: AMD Athlon(tm) 64 Processor 3000+ (2493.04-MHz 686-class CPU)
  Origin =3D "AuthenticAMD"  Id =3D 0x20ff0  Stepping =3D 0
 =20
=46eatures=3D0x78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE=
,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2>
  Features2=3D0x1<SSE3>
  AMD Features=3D0xe2500800<SYSCALL,NX,MMX+,FFXSR,LM,3DNow+,3DNow>
  AMD Features2=3D0x1<LAHF>

I would need AMD Athlon(tm) 64 Processor 3000+ (2493.04-MHz 686-class CPU) =
or=20
similar.

Thanks,
Nicolas.
