;The first line is the number of lines/definition in this archiver.bb2 file...
;It is very important; do not change.  It allows modifications to the
;file format to be transparent to older programs.

;ARCHIVER.BB2, archiver control file for FM/2, AV, XBBS-OS/2 & XGROUP
;KEEP A COPY OF THIS ORIGINAL FILE FOR INFORMATION LATER!

; $Id: archiver.tmp 429 2006-08-14 04:16:39Z root $

;Format for this archiver.bb2 file (each entry has 21 lines):
;
; 1st line:  archiver id (i.e. ARC, LHARC, PKZIP, etc.) for human consumption
; 2nd line:  normal extension for archives without period  (i.e ZIP, ARC, LZH)
; 3rd line:  offset into file to signature (leave blank if no signature)
; 4th line:  list command
; 5th line:  extract command
; 6th line:  extract with directories command
; 7th line:  test archive command
; 8th line:  add/create command
; 9th line:  add/create with paths command
;10th line:  add/create & recurse command
;11th line:  move command
;12th line:  move with paths command
;13th line:  delete command
;14th line:  signature (case sensitive, leading spaces count!)
;15th line:  startlist string
;16th line:  endlist string
;17th line:  old size position (0-based, -1 = not available)
;18th line:  new size position  (0-based, -1 = not available)
;19th line:  file date position (0-based, -1 = not available) [,type of date (0 for none)]
;20th line:  number of elements in dates (for "03 June 92" would be 3)
;21st line:  file name position (absolutely required, of course; -1 = last pos)[,name is last (1 = TRUE, n/a w/ -1 pos)[name is next line (1 = TRUE)[,name is first line, then rest of data (1 = TRUE)]]]
; see ZOO entry for example of -1 in file name position
; see LH entry for example of name is last
; see RAR 2.00 entry for example of name is first
; check listings generated by these programs for clarification

;ARCHIVER AUTHORS:  MAKE A STANDARD!

;A semicolon marks a comment.  They may appear at any point *except*
;within the 21 lines of an archiver definition entry.  Comments are ignored.
;Archiver definition entries that contain numeric values may have trailing comments.
;Archiver definition lines that contain strings do not support trailing comments.

;Blank lines are ignored except within a 21 line archiver definition entry.
;A blank line with a definition entry will be treats as either an empty string
;or the number 0, depending on what content is expected for the definition line.

;Note that all archiver command strings should include the archiver's parameter to
;prevent it from prompting for input!  Also note that archive types are checked
;in order of their listing in this file.  Finally, this file is set up for
;the archivers I had lying around. If yours are different versions, you may
;have to modify this file.  All archivers are OS/2 (or FAPI) versions.
;DOS archivers may work with FM/2, but it'll be up to you to set them up.

;Supported date types:
;--------------------
;                       No date in data         0
;02-31-98  23:55:32     mm-dd-yy hh:mm:ss       1
;31 Feb 98 23:55:32     dd-Mmm- yy hh:mm:ss     2
;31 Feb 98  11:55p      dd Mmm yy hh:mmA        3
;98-02-31 23:55:32      yy-mm-dd mm:mm:ss       4
;31-02-98  23:55        dd-mm-yy hh:mm          5

; Dash (-) and slash (/) separators are both supported.
; Both 2 digit and 4 digit years are supported.
; 2 digit years slide about 1980.

;The positions specified in an archiver defintion are word numbers, where a
;word is something separated by whitespace.  Counting starts at zero (0).
;Minus one (-1) usually indicates the item does not exist.  The exception is
;the file name position (line 21), where -1 indicates that the filename is
;the last entry on the listing line.  This allow files names with spaces to
;be supported.

;How archiver selection works (for the curious):

;The archive selector scans the known archivers in the order in which they
;are defined.  The selector first tries a signature match, unless this is
;suppressed in the settings.  If there is no signature defined or if
;the signature match is suppressed, the selector checks to see if the file
;extension matches.  The matching entry defines the commands used for the
;various archiving operations and supplies parameters that enable the archiver
;outputs to be parsed.

;Warning:  I'm told there's a bug in some versions of 4OS2 that can cause
;a call to an archiver to fail if the archiver has an extension (i.e.
;UNZIP works, UNZIP.EXE doesn't).  If things fail for no apparent reason
;and you're using 4OS2 you might keep it in mind.
;
;The FM/2 code for accessing and using this information is in avl.c, avl.c and
;arccnrs.c and is freely available for use in in your own projects under
;the terms of then GNU GPL2 license.

; Entry #26 - ZIP 1.9/UNZIP 5.0 (available in 32-bit versions).
;ZIP/UNZIP should work with PKZIP 2.04 files.  Saves EAs well.  Won't
;extract a file stored with path without the path (actually, this seems
;to be fixed now.  Maybe.  There are dozens of versions floating around;
;you don't pays your money and you takes your chances).  If you have a
;version that won't extract files with paths without the paths, there's
;a workaround -- change the line "UNZIP.EXE -jo" below to "UNZIP.EXE -o".
;Because of broken ZIP archives floating around everywhere, this is here
;without the version flag in the signature (should really be PK\x03\x04\x14).
;Damnit, it looks like Katz's own software is what does the botching.  So
;much for the keeper of the ZIP standard...  Zip still seems to have to
;have erratic problems with creating archives with some pathnames...

;Notes on modifying/updating this file:
;=====================================

;You can add as many archivers as you like to this file.
;here are some suggestions on how to go about it:

;List an archive with the archiver, redirecting to a disk
;file (ex. "ARC l AFILE.ARC > TEMP.").  Load the resultant
;file into a text editor.  Clip out the startlist and endlist
;strings and paste directly into this file on the appropriate
;lines; prevents errors due to typos when copying manually.
;Count the positions of filename, date, etc. and place on the
;appropriate line.  Now run the archiver redirected to a file
;to get its help screen (ex. "ARC > TEMP." or "ZOO h > TEMP.").
;Look for the various command options (extract, list, etc.) and
;put them into the file on the appropriate lines -- remember to
;add the modifiers to prevent the archiver from stopping to ask
;questions!  You could be in deep doo-doo if it's a detached
;process.  While it may seem a pain in the arse to have to
;edit this file when an archiver changes its command structure
;or list format, at least it's something within your control;
;you don't have to wait for an update to FM/2.  That means if I
;die tomorrow you'll still be able to use FM/2 for years to come.

;Here's an example of an ARC listing (5.12mpl, command "ARC l"):

;----------------cut here----------------------
;Name          Length    Date
;============  ========  =========    <--this line is start-of-list
;MAKEFILE           374  28 Nov 89
;QSORT.C          14279  29 Nov 89
;QSORT.EXE        24629  29 Nov 89
;STUFF.H            371  29 Nov 89
;        ====  ========               <--this line is end-of-list
;Total      4     39653
;----------------cut here----------------------

;Note the filename is in position 0, old length in position 1, and the
;date starts in position 2, with 3 parts, and there's no new length
;field (so it'd be -1).  Compare that to the archiver entry for
;ARC 5.12mpl above and you should get a feel for what all those fields
;mean.  Here's a diagram of how a file line breaks down:

;STUFF.H            371  29 Nov 89
;  ^                 ^   ^
;  |                 |   |
;  |                 |   +--Date starts in field 2, 3 parts (29, Nov, and 89)
;  |                 |
;  |                 +--Old file length, field 1
;  |
;  +--Filename, field 0 (count from 0, not 1)

;If you're adding an entirely new archive format, note that you can
;use 'C'-style \x<hexnumber> on the signature line in this file.
;For example, the \x1a in ARC 5.12mpl's signature line means FM/2 will
;look for an ASCII 26 (text EOF marker) in position 0 (first byte, as
;indicated by ARC's line 3, the offset into a file for the signature)
;of a file to determine if it's an archive.  If line 3's offset is
;negative, FM/2 looks from the end of the file instead of the beginning.
;You can usually figure out what an archiver's signature is by looking
;at a few archives with a file viewing program like Vernon Buerg's
;LIST.  By all means send me anything new you figure out for inclusion
;in future releases.

;You can have several entries for one type of archive in this file.  FM/2
;tries entries sequentially to list the file until it finds one that works.
;If the first entry for a signature doesn't work, and FM/2 finds one that
;does, it moves that entry to the top of the list and rewrites ARCHIVER.BB2
;to make future accesses faster.  This allows me to list everything I can
;get entries for and let FM/2 sort out what the user actually has that works.
;It also lets you, the user, create archives with more than one archiver that
;produces the same sort of archive (or with different switches, like one with
;LHArc producing -lh5- compression and one with it producing old, compatible
;-lh1- compression).

;Always end file with blank line or comment
