I'd like to setup command line switches that are dependent on other
switches, similar to what rpm does listed below. From the grammar below
we see that the "query-options" are dependent on the query switch,
{-q|--query}. Can "optparse" do this or do I have to code my own
"thing"? Thanks.
QUERYING AND VERIFYING PACKAGES:
rpm {-q|--query} [select-options] [query-options]
...
query-options
[--changelog] [-c,--configfiles] [-d,--docfiles] [--dump]
[--filesbypkg] [-i,--info] [--last] [-l,--list]
[--provides] [--qf,--queryformat QUERYFMT]
[-R,--requires] [--scripts] [-s,--state]
[--triggers,--triggerscripts]
