For all of the following, first connect
to [tihost] at [tiport], get past the connection banner,
and send  the v: and O: transactions(any others?), etc.

GET /[tihost]:[tiport]/M/[tinodeid]
Algorithm for sending a menu html document:

		Use techinfo transaction (s: ???) to get node
		information.  Need the Title,  the short source and full source names.
		Make this a subroutine because it'll be called a lot.

		Print out the title twice: "<Title>%s</title>\n<H1>%s</h1>", doctitle, doctitle

		Print <ISINDEX>

    Print: "The source of this menu is <a href=\"/%s:%s/source:%s\">%s</a>.\n\
      <a href=\"/%s:%s/info/%s\">More information</a> is available
       about this menu.<p>\n",  tiserver, tiport, shortsource, longsource,
		   tiserver, tiport, tinodeid.

		Send the list of menu items.
    Use techinfo transaction w:2:[tinodeid]:1 to get
		all of the items in this menu.  See below for how to
		deal with each item.

		Print: "Return to the <a href=\"/%s:%s/M/0\">Main Menu<\a> at %s.\n"
		 tiserver, tiport, tiserver.


How to send a LIST OF ITEMS (either for search or menu expansion):

		Print: "To see the size or other information each item below,
		follow the \"Info\" link.\n"

		Print: "<pre>\n"

		For each menu item from the w: or searching transaction:
		    Figure out the type, nodeid, and title of the item

		    Figure out the number of levels deep this item is

		    Print a single line:
		    <a href=\"/%s:%s/%c/%s%s\">%*s%s</a>    <a href=\"/%s:%s/info/%s\">Info</a>\n
		    %s:%s		tiserver, tiport
		    %c		I, D, or M
		    %s		the nodeid of the child
		    %s		If type is I, then ".gif", else "".
		    %*s		numlevels * indentlen, ""
		    %s		Title of the child
        %s:%s		tiserver, tiport
		    %s		the nodeid of the child

		Print </pre> at the end of the list of menu items.

GET /[tihost]:[tiport]/D/[tinodeid]
Algorithm for sending an ascii text html document:

		Get node information -- use the same subroutine as for getting menu info.
		Need the Title,  the short source and full source names.

		Print: "<Title>%s</title>\n<H1>%s</h1>", doctitle, doctitle

		Print: "The source of this document is <a href=\"/%s:%s/source:%s\">%s</a>.\n\
      <a href=\"/%s:%s/info/%d\">More information</a> is available
       about this document.<p>\n",  tiserver, tiport, shortsource, longsource,
		   tiserver, tiport, tinodeid.

		Print: <plaintext>

		Use the t: transaction to get the text of the document, and then send it
		verbatim.  Is a terminator necessary?


GET /[tihost]:[tiport]/I/[tinodeid].gif
Algorithm for sending a GIF image:

		Figure out if WWW images can have html at the beginning of them.
		Such as: <title> or <h1>.  If they can, then
				Get node info.  Print <title> and <h1> and <isindex>

		Use the t: transaction to get the 8-bit contents of the document, and
		send them verbatim.


GET /[tihost]:[tiport]/[type]/[tinodeid]?[word]+[word]
				Results of a search.  Not yet certain how this works.


GET /[tihost]:[tiport]/source/[sourcename]
				Detailed contact information about the short sourcename.

		Use techinfo transaction (???) to get all informaton about the
		sourcename.

		Print: "<Title>Information about \"%s\"<\title>\n\
		    <H1>Information about \"%s\"</h1>\n",
		fullsourcename, fullsourcename

		Print: <pre>
		Print out  both short & long source name, telephone numbers, people's names,
		email addresses, etc, for this source.
	  Print: </pre>

    if tiserver is equal to local_tiserver, then
		  Print: <p>A  list of <a href=\"/%s:%s/D/%s\">all sources</a> is available.\n",
		    local_ti_sources_nodeid


GET /[tihost]:[tiport]/info/[tinodeid]
				Detailed information about the document, menu, or image.

		Get the node information -- use the same subroutine as for a
		menu or plain text document.

		Print: "<Title>Information about \"%s\"</title>\n\
		    <H1>Information about \"%s\"</h1>\n\n", title, title.

		If this node is a plain ascii text or image document, then
				use the t:[nodeid]:0:20 transaction to get the total # of bytes
				and the last modification date of the file.

		Print: "<pre>\n"

		Print: "Title:    <a href=\"/%s:%s/%c/%s%s\">%s</a>\n
		tiserver, tiport, itype, nodeid, ".gif" or "", title

		If the itype is D or I, then
			  If the totalbytes is < 2048 then
		        Print: "Size:     %d bytes.\n", totalbytes
		    else
		        Print: "Size:     %dK bytes.\n", totalbytes/1024

		    Print: "Modified: %s\n", lastmodtime

		Print: "Source:   <a href=\"/%s:%s/source/%s\">%s\n
		tiserver, tiport, shortsource, longsource

		Print: "Type:     %s\n",  Switch (itype), "Menu", "Plain text", "Image".

		Print: "Keywords:\n"

		For each keyword on the keyword list (separated by commas):
		    Print: "          <a href=\"unimplemented\">%s</a>\n", keyword

		Print: "Nodeid:   %s\n", nodeid

		Print: "</pre> <p>\n\n"

		If the type of this thing is a menu, then
		    Print: "You can view an Outline of this menu <ul>\n\
		     <li><a href=\"/%s:%s/outline/2/%s\">two levels deep</a>,\n\
         <li><a href=\"/%s:%s/outline/3/%s\">three levels deep</a>, or\n\
		     <li><a href=\"/%s:%s/outline/4/%s\">four levels deep</a>.</ul> <p>\n\n"
			tiserver, tiport, nodeid, tiserver, tiport, nodeid, tiserver, tiport, nodeid

		Print: "Show the  <a href="/%s:%s/path/%s">path</a> to
		   this item from the <a href=\"/%s:%s/M/0\">Main Menu</a>.		


GET /worldwide-techinfo
				A menu of all TechInfo servers. Remember to replace penninfo-gopher
				with gopher://gopher.upenn.edu/
