build a selection that contains a common atom type (say CA for the
alpha carbon) and then the desired residue names, either with a
regular expression or through logical or). from this selection
function you can now get multiple properties in one go, e.g. resid,
resname, segid and in return you will get a list of lists that
contains the requested property triple for each matched atom in the
selection (and since there usually is only one alpha carbon per
residue, that will be identical to one triple per residue).

that list you can either output to a file, or process further with
additional tcl scripting.
