MASMTidy tidies MASM *.asm assembler source, aligning it in four columns.
It also converts all your operators to lower case.  It does not reorder
the code in any way or insert or remove anything.
It handles single line comments, tail comments and comment | style
comments.
To convert a single program, type:
  java.exe -jar C:\com\mindprod\masmtidy\masmtidy.jar myprogram.asm
The results replace the old file, so you had better make a
backup just in case this is not what you want.
You can also list several files on the command line:
  java.exe -jar C:\com\mindprod\masmtidy\masmtidy.jar myprogram.asm C:\mydir\another.asm
To use convert the current directory of asm files:
  java.exe -jar C:\com\mindprod\masmtidy\masmtidy.jar .
Sorry no wildcards, or negative wildcards, just . , and ..
DON'T USE WILDCARDS unless you deeply understand how they
work. See http://mindprod.com/jgloss/wildcard.html. Windows
expands them, not MASMTidy, and feeds them to MASMTidy (or any other program)
as a giant list of all the directories and files in the
current directory. MASMTidy will thus tend  process all the files
in your directories, when you just meant to process the files in
the current directory.
The -s switch makes all subsequent directories searched
recursively to include all their subdirectories.
e.g.
  java.exe -jar C:\com\mindprod\masmtidy\masmtidy.jar -s E:\com
will fix all *.asm files in the E:\com directory tree,
ignoring other types of files.
The -q option switch suppresses output. Without it, you see
a list of the files it changed.
If you have the jar extension set up as executable, you can
abbreviate:
  C:\com\mindprod\masmtidy\masmtidy.jar .
CONFIGURING
You can change the column widths and suppress conversion of operators to
lower case by modifying the constants in MASMSTate.java and recompiliing.
Here is how they default:
   /**
     * configure false to allow mixed case operators in second column.
     */
    private static final boolean LOWER_CASE_OPERATORS = true;
    /**
     * configure 0-based column for the third operand column
     */
    private static final int COL_FOR_OPERAND = 25;
    /**
     * configure 0-based column for the second operator column
     */
    private static final int COL_FOR_OPERATOR = 15;
    /**
     * configure 0-based column for the fourth commend column
     */
    private static final int COL_FOR_TAIL_COMMENT = 40;
