* This starts up a 1-line command that's defined to be an "index gateway"
* Currently this is only implemented for VMS
*
* Currently "SEARCH", "SINCE", "BEFORE", "VERSION", "GO4LINK", "FTPLINK"
* and "EXELINK" are supported. "KABOOM" is a debugging "feature."
*
* "SEARCH" performs a case-insensitive search for terms, without any
* interpretation of printable characters, with leading and trailing spaces
* trimmed, and with embedded spaces treated as the Boolean OR. The search
* corresponds to the expectations of the client's Boldit() routine. SEARCH
* may be suffixed by &, |, ~& or ~| to select the VMS /MATCH= operand, and
* override the default, implicit /MATCH=OR.
*
* "SINCE" and "BEFORE" return lists of files modified since or before
* the supplied term, a date specification.
*
* "VERSION" displays version information about the server. It's not really
* a "search" even though it acts like one.
*
* "GO4LINK" uses a pseudo-SearchString (the Internet address of a Gopher
* server) to create a link tuple which the client can use to connect to
* a server there.
*
* "FTPLINK" uses a pseudo-SearchString (the Internet address of an FTP
* archive) to create a link tuple which the client can pass to the server's
* FTP gateway.
*
* "EXELINK" uses a pseudo-SearchString (the exec script arguments the user
* wishes to pass) to create a link tuple which the client can pass to the
* server for execution of a script. The type of output to be expected by
* the client and the script to be executed are specified with the execlink
* keyword. E.g., "Path=7$exelink Xscriptname" where "X" is the Type=
* entry for the link tuple to be generated, and "scriptname" is the script
* file name to be used in the Path=exec:<args>:scriptname tuple entry. The
* <args>, if any, are supplied by the user as the terms of the pseudo-search.
*
* "KABOOM" causes an access violation for debugging purposes. It will only
* work when the local host alias and client requestor match the values
* specified in the environment variables (symbols or logicals) named
* GOPHERD_KABOOM_HOST and GOPHERD_KABOOM_CLIENT, respectively.
*
* The command must write output in the same format as the GrepIndexQuery()
* output is formatted (that is, the result must be a menu of one entry or
* more).
*
