If we cannot find the exact application name for centos, say MATLAB
for centos does not exist, so we must search for 'Mathematics
laboratory for centos' ? Or if Pspice for centos does not exist so we
must search for 'Electronics circuit schematics editor and simulator
for centos' ? If there any reference site that we can select centos
application with respect to their functionality deffinition but not
just the application name?
