// OSlite 1.1 by Enrico Demarin 20 Sept. 1994 , 0:55 //
// //
///////////////////////////////////////////////////////////////////////
OSlite converts an OS/2 executable to a compressed CMD file.
It requires 4OS2 2.00 or higher, an HPFS partition, GZIP (not included)
and skip.exe. (skip.exe requires EMX 0.8H runtime, not included :).
You can found both EMX runtime and GZIP on ftp.cdrom.com or
ftp-os2.nmsu.edu.
I tested Oslite with GZIP 1.2.4 (18 Aug 93), 4/OS2 2.00
patchlevel D, EMX 0.8H patchlevel 10, OS/2 2.11.
I used a (slooooow) AMD 386sx-33 (8 Megs of RAM) and a
(not the fastest...) 486DLC-40 (8 megs of RAM). The performance
is acceptable on the 486.
////////////// INSTALLATION ///////////////////////////////////////////
To install OSlite, you must :
1 - Define the temporary file path used by OSLite system
in the environment variable OSLITE.
The temporary path MUST be in a HPFS drive.
Ex. SET OSLITE=E:\TEMP
2 - Copy the files lthdr.cmd, oslite.cmd ,skip.exe, unlite.cmd
in the path. You MUST also have Gzip in the path.
To convert old Oslited files and use the new decompression header,
you must unlite the files and compress the files again.
//////////////// PACKAGE //////////////////////////////////////////////
Commands:
OSlite.cmd : compresses an executable
Unlite.cmd : decompresses an Oslited executable.
OSlite.btm : OSlite.cmd packed with 4os2's batcomp (faster ?)
Unlite.btm : Unlite.cmd packed with 4os2's batcomp (faster ?)
lthdr.cmd : The decompression header
skip.exe : (used by lthdr.cmd)
skip.c : Source file of skip.exe (EMX 0.8h Patch 10 was used)
(so you can guess the syntax and the purpose :)
**************************** WARNING **********************************
Skip.exe, gzip.exe, eatool.exe and lthdr.cmd MUST remain uncompressed.
(and DONT'T pack lthdr.cmd with 4OS2's batcomp !!)
//////////////// HISTORY /////////////////////////////////////////////
version 1.1:
o Fixed bugs almost everywhere... (sorry...:(
o Revised command line options of both Oslite.cmd and Unlite.cmd
8-) Added support for Extended Attributes (now EAS are not lost anymore)
This option needs EATOOL in the path. (you can use the /NOEAS option
to skip EA saving).
8-) Added CTRL-C and CTRL-BREAK handling.
version 1.0:
First public release.
//////////////// PLANS //////////////////////////////////////////////
Ability to create compressed .CMD from other file types ?
(for example, compress an .INF and create a .CMD that
decompresses the INF and shows it with VIEW.EXE)
A REXX version of OSLite (no more 4OS/2 required) ?
Tell me what do you think about it.
