+# Help messages
+gw.help.general: You
+ have triggered the "help"-information on the Email gateway. \n\n
+ This preliminary service is a very early alpha release of a Email service\n
+ which acts as a Z39.50-client (origin). \n\n
+ With this service you can connect to several Z39.50-targets. Your Email\n
+ body consists of one or more commands. Each command must start on column\n
+ zero; otherwise it will be ignored. Also, everything AFTER the first\n
+ empty line in your body is ignored. Thus, you probably do not have to\n
+ delete your signature in the end.\n\n
+ All your requests will be logged. Hopefully you will get a reply with\n
+ the result of your queries in a minute or two. If you don't something\n
+ probably went wrong. Hopefully, we will be able to see what went wrong\n
+ by examining the log files.\n\n
+ This is what you do:\n\n
+ * First you must select a target (i.e. a host with a Z39.50-interface\n
+ to one or more databases) with the "target" command. For example:\n
+ \ttarget dranet.dra.com\n
+ * Second, select the databases in which you wish to search, with the\n
+ "base" command. For example:\n
+ \tbase drewdb\n\n
+ * Now you are ready to issue real queries by using the "find"-command.\n
+ The query consists of one or more search words. You can perform boolean\n
+ searches by using the operators "and", "or" and "not". For example:\n
+ \tfind computer and knuth\n
+ If the target supports it, you may also direct the search to special\n
+ indexes by using qualfiers. For example, the following query will search\n
+ for "computer" in the "title"-index and "knuth" in the "normal" index:\n
+ \tfind ti=computer and knuth\n\n
+ * If the query succeeds, you will be informed with the number of hits.\n
+ To display the records use the "show"-command.\n
