<Main defaults>
Save path information in archive
Save long filenames
Save/restore file date-time created and accessed in Win95/98/ME/2K/XP
Don't save drive and root in path information
Display comment ANSI sequences with built-in display handler
Prompt before overwriting output files
Use method 1 compression
Use binary mode
Use ! as list file symbol
The "ac" command is an abbreviation for "u -u2 -jb"
The "cc" command is an abbreviation for "y -jb"
The "dc" command is an abbreviation for "d -jb"
The "lc" command is an abbreviation for "l -jb*"
The "vc" command is an abbreviation for "v -jb*"

(ARJ32) Save/restore file date-time created and accessed in Win95/98/NT

ARJ32 uses OEM codepage by default. The "-hy" option sets ARJ32 to use
the ANSI codepage which is the Windows graphical environment default. ARJ32
self-extracting archives should be built using the "-hy" option.

Environment variable setting:
set arj_sw=-jyry -jv -i1
set arj_sw=c:\arj.cfg

(ARJ32 uses ARJ32_SW instead of ARJ_SW)

set arj32_sw=-hy

ARJ DOS errorlevels:

0 -> success
1 -> warning (specified file to add to archive not found,
specified file to list, extract, etc., not found,
or answering negatively to "OK to proceed to next volume…"
prompt)
2 -> fatal error
3 -> CRC error (header or file CRC error or bad password)
4 -> ARJ-SECURITY error or attempt to update an ARJ-SECURED archive
5 -> disk full or write error
6 -> cannot open archive or file
7 -> simple user error (bad parameters)
8 -> not enough memory
9 -> not an ARJ archive
10 -> XMS memory error (read or write)
11 -> user control break
12 -> too many chapters (over 250)

The batch statement IF ERRORLEVEL 0 … means
if the errorlevel is EQUAL TO or GREATER THAN 0.

If the first two characters of an ARJ comment are "))" in a self-extractor,
then the self-extractor will accept the appended line as its command line.
