+cpuinfo2cpuflags (guess CPU_FLAGS_X86 flags for the host)
+
+cpuinfo2cpuflags is a tool to guess CPU_FLAGS_X86 flags for the host.
+
+Call the cpuid instruction to obtain the supported CPU feature bits
+instead of reading the preprocessed values from Linux-specific 
+/proc/cpuinfo. This increases portability across systems and accuracy of
+information -- supported instructions depend on the version of the
+program rather than the Linux kernel.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
