+gw.help.target: Command:\n
+ \ttarget <host>[:<port>]\n
+ \n
+ The target command selects exactly one target <host>. The <host>
+ is a normal internet domain hostname. The optional <port> argument
+ specifies the port number to use. Normally, this does not need to be
+ specified.
+ \n
+gw.help.base: Command:\n
+ \tbase <base1> <base2> ...\n
+ \n
+ The base command selects one or more databases. However, some
+ targets do not allow the selection of more than one database.
+ \n
+gw.help.find: Command:\n
+ \tfind <query>\n\n
+ The find command issues a search request based on the specified
+ <query>. A query consists of one or more <search-element>s separated
+ by boolean operators <bool-operator>, i.e.:\n
+ \tquery = search-element bool-operator search-element ...\n\n
+ There are three boolean operators (| means or):\n
+ \tbool-operator = and | or | not\n\n
+ A search-element has three forms. The first and simplest is
+ when it consists of one or more search-terms as in:\n
+ \t<search-element> = <search-term> ...\n\n
+ In the second form, qualifiers are specified:\n
+ \t<search-element> = <qualifier> <relation> <search-term> ...\n\n
+ A qualifier directs the search to a specified index register. The
+ relation is:\n
+ \t<relation> = > | < | >= | <= | = | <>\n\n
+ The third type of <search-element> is the result-set reference:\n
+ \t<search-element> = s=<name>\n\n
+ Parentheses may be used to create recursive definitions.\n\n
+ Some examples, may be in order:\n
+ \tfind network\n
+ This query consists of one <search-element>, which in turn consists of
+ one <search-term>. The query searches for the word "network".\n\n
+ \tfind computer network\n
+ This is the same as above, but there are two search terms. The
+ phrase "computer network" is searched.\n\n
+ \tfind ti=computer and au=knuth or donald\n
+ There are three <search-element>s. The first and second <search-element>
+ use qualifiers; the last one doesn't. The search is equivalent to:\n
+ \tfind (ti=computer and au=knuth) or donald\n
+ If the 'or' is to be applied to "knuth" and "donald", one could use:\n
+ \tfind ti=computer and (au=knuth or donald)\n\n
+ \tfind computer and s=2\n
+ Here, the <search-term> "computer" is and'ed with result-set "2".\n
+gw.help.show: Command:\n
+ \tshow <show-spec> ...\n\n
+ The show command retrieves records. A <show-spec> is a combination
+ of record position specifications and a presentation format
+ specification. A show command with no <show-spec> retrieves
+ 10 records and displays them in the full format. A show-spec
+ of the form:\n
+ \tf = <type>\n
+ sets the the format to <type>. Currently, there are three formats:
+ 0 - full, 1 - medium, 2 compact format. Record positions can
+ be specified by the form:\n
+ \tp = <from> - <to>\n
+ Here <from> and <to> are two integers specifying the record
+ positions.\n
+ Example:\n
+ \tshow p=2-7 p=9-10 f=1\n
+ Records 2 through 7 and 9-10 are shown in format 1.\n
+gw.help.def:\n
+ \tdef <setting> <value>\n
+ The def command sets/gets various settings. Setting is one of:
+ \tf - display format to be used in show\n
+ \tautoshow - number of records to show after a find\n
+ \tdefaultshow - number of records to retrieve in a show command\n
+ \tlang - conversation language\n
+ \n
+ \treset - resets the settings to their defaults values\n
+ \tshow - show current settings\n
+gw.help.account:\n
+ \taccount <account>\n
+ Sets authentication string. Necessary for some targets.\n
+gw.help.status:\n
+ \tstatus\n
+ Displays information about previous result sets and how they were obtained.\n
