/********************PicLink 1.0 By Chris Murray*********************
This program creates a multitude of HTML files each of which displays
a picture, and each of which is linked to other views. This is to create
a virtual tour of still photos, allowing the viewer to look in different
directions from a certain vantage point, and move forward from point to
point.
One of the many files put out by this program is listed below:
TuHS Tour View 001E
Location 001 looking East
Go:
Forward
To Main Map
Turn:
Left
Around
Right
The program creates the links from a simpler expression of the connectivity
encoded in a text file that the program reads. A Sample file
is listed below: (the comments are indicated by <-- and are not
in the real version of the file :- )
001N. <-- Just a view. location 001, looking North. 001 can be any text.
001E-018E. <-- from location 001 looking East, the forward link is to 018 East
001S-004S.
001W.
004N-001N.
! this is a legal comment (! must be in the first column)
004E.
004S-006S. <-- and so on and so forth
004W.
006N-004N.
006E.
006S-007S.B <--This HTML file has its body in a separate file B006S.HTM
006W.
007N-006N.
007E.
007W-003N.
007S-008S.
008N-007N.M <--This HTML file has an image map in file M008N.HTM
008E-009E.
008S.
008W.
018E-002E.
018W-001W.
018S.
018N-019N.
002E-012E.
012E-003E.
003N. <--locations need not be entered in order.
003E.
003S.
003W.
. <--End of file marker. the periods are obligatory, and all
<--syntax is checked before the program proceeds with anything.
