15: ** History:
16: **
17: ** 4 Dec 90: Written from scratch (NP)
18: ** 11 Feb 91: Code written by TBL so that the browser could be linked with
19: ** code produced by Bernd Pollermann, enabling access to the
20: ** data on CERNVM. This involved changing the code to handle file
21: ** numbers rather than file pointers.
22: ** 18 Mar 91: The feature of history mechanism was included, enabling a
23: ** record of previous nodes visited to be kept.
24: ** 6 Apr 91: When a node is accessed, it is immediately read into a
1.40 frystyk 25: ** buffer, in an unformatted state, as soon as the connection is
1.1 timbl 26: ** made, so that the server is freed as quickly as possible.
27: ** The program now also uses the additional modules HTBufferFile.c
28: ** and HTBufferFile.h.
29: ** 17 Apr 91: Can be used on machines running ANSI C and ordinary C.
30: ** 10 May 91: Formatted text is stored in a linked list buffer which allows
31: ** scrolling and better page breaks in the middle of text.
32: ** Code incorporated by Tim BL, to enable anonymous FTP.
33: ** 21 May 91: Accepts various parameters on the command line.
34: ** 19 Aug 91: Currently available in Unix, VAX/VMS and MVS environments.
35: ** 21 Nov 91: Character grid uses new architecture. (TBL)
36: ** added -w option, new commands, print,
37: ** ... See Features.html for further details
38: ** 16 Jan 92: Put in VIOLA-compatible options - see \017 characters.
39: ** \017 and \016 bracket user-selectable input.
40: ** 27 Feb 92: New handling of user input, enhanced command syntax. (JFG)
41: ** 18 May 92: PS command see ifdef SLAVE_PRINTER (DR/TBL)
42: ** 6 Oct 92: Painful recovery from someone(?)'s attept to pretty print.(TBL)
43: ** Please see coding style guide before changing indentation etc!
44: ** Mar 93: Force on HTFile's HTDirAccess and HTDirReadme flags.
1.8 duns 45: ** 3 Nov 93: (MD) Changed vms into VMS
1.99 frystyk 46: ** (MD) Assigne OUTPUT in main, not at initialize (VMS only)
1.1 timbl 47: **
48: ** Compilation-time macro options

50: ** REF_MARK Printf string to be used for printing anchor numbers
51: ** END_MARK String to be used to denote the end of a document
