Doom LMP Utility System
Version 2.10, 05-22-95
Copyright 1995, Raymond Chi

========
Overview
========
LmpUtil is a program that you can use to display detailed information
about a LMP file. It allows you to set the LMP file version, change
recording player to a different active player, convert 1.0 - 1.2 LMP to
the newer LMP format used with Doom 1.4 - 1.9, remove a section of LMP,
and the ability to add some idle tics at the end of the LMP.
It works with any kind of LMP generated by any version of Doom / Doom II.
Heretic LMP is supported, but requires a special parameter to tell LmpUtil.
============
Installation
============
1) Make a directory and copy all lmputil files to it.
2) add the directory to your path statement in autoexec.bat
Or, if you are using 4dos/Ndos, create an alias that points to
lmputil.exe instead of add the directory to your path.
==========
What's New
==========
The -chop command is implemented. So your -timer 20 lmpfile can now be
exactly 22 minutes long.
You can now omit the .lmp file extension in all cases. If the file
specification doesn't contain any period, then the ".lmp" extension is
added automatically.
The -cut command is removed from the help screen, but it is still
implemented should you want to play with it.
LmpUtil can now display info about multiple files. So you can do
lmputil *
and it will print info on all *.lmp files.
============
Sample Usage
============
To display information about a LMP, simply type :
-> lmputil lmpfile
Change the recording player to the next available player :
-> lmputil -viewer lmpfile
Change the LMP file version to 1.9 :
-> lmputil -ver 1.9 lmpfile
You can combine -viewer and -ver. For example :
-> lmputil lmpfile -ver 1.7 -viewer
will set the LMP version to 1.7, and change the recording player.
In LmpUtil v2.00, wildcards support is added for -ver and -viewer. Say you
want to convert all the LMPs in your current directory to 1.9, the command
to do it is :
-> lmputil -ver 1.9 *.lmp
To convert a 1.1 or 1.2 LMP to the newer LMP format, type :
-> lmputil -convert source target <optional version>
The source and target must not be the same file. Although the program tries
to detect if the 2 files are the same, it will fail if you deliberately
tries to fool it. And in that case, will corrucpt the source file.
If ver is not specified, the target file will have LMP version stamp 1.9.
Although the order of parameter doesn't matter, i.e., you can specify the
lmpfile either before or after the -viewer, there must be a version number
follow -ver; a source, a target, and a optional version after -convert.
So you cannot, for example, do :
-> lmputil -viewer -ver lmpfile 1.6
because a lmp version is expected after -ver.
To add 100 seconds of waiting time at the end of your LMP, do :
-> lmputil -wait 3500 source.lmp target.lmp
the 3500 represent 100 seconds, because 35 gametics is 1 second.
To remove the first 10 minutes of LMP, do :
-> lmputil -cut 1 21000 source.lmp target.lmp
-cut and -wait expect time to be specified in gametics, not seconds.
To convert from time to gametics is very easy :
1) convert the time to seconds
2) multiply the seconds by 35.
You can use either - or / as the parameter indicator. All of the above
examples can be done with / instead of -. So you can do, for example,
-> lmputil /ver 1.6 lmpfile -viewer
If -convert, -cut, -wait is specified, anything after the required parameter
will be ignored. So if you use -heretic, use it as the first parameter.
