+Description: CPU feature checking - common back-end
+ The packages in the isa-support family probe for microprocessor Instruction
+ Set Architecture features such as SSE3. By refusing to install on machines
+ lacking a required feature, they allow ISA requirements to be handled in
+ terms of package dependencies.
+ .
+ This package provides the feature-probing infrastructure. To assert a CPU
+ requirement, other packages can pre-depend on one of the individual
+ feature-specific packages:
+ .

+ armv6-support, armv7-support, armv8-support, vfp-support, vfpv2-support,
