This is more consistent with standard man-pages headings
and layout.

.SH HARDWARE CAPABILITIES
Some libraries are compiled using hardware-specific instructions which do
not exist on every CPU.
Such libraries should be installed in directories whose names define the
required hardware capabilities, such as
.IR /usr/lib/sse2/ .
The dynamic linker checks these directories against the hardware of the
machine and selects the most suitable version of a given library.
Hardware capability directories can be cascaded to combine CPU features.
The list of supported hardware capability names depends on the CPU.
The following names are currently recognized:
