To run BatchResourceUpdater, you can do the following:

BatchResourceUpdater test.bru

Where "bru" files are actually just XML files, with the following format:

<?xml version="1.0" encoding="UTF-8" ?>
<BatchResourceUpdate>
  <Copy>
    <Source>...</Source>
    <Destination>...</Destination>
  </Copy>
  ...
  <Remove>...</Remove>
  ...
</BatchResourceUpdate>

The <Copy> and <Remove> blocks may come in any order and any number of them.
The source, destination, and remove values are specifications of either files
or resource IDs, for example:

File:		file1.bmp
Resource:	shell32.dll|BITMAP|100|1033

PE Files must have an extention of:
	exe, dll, sys, ocx, mui, drv, cpl, efi, com, fnt, msstyles, scr, ax, acm, ime, pe

For more examples see the examples zip file.

The <Copy> block may have more than one destination, but only one source.
It also can have an "overwrite" attribute:
	<Copy overwrite="always|never|only">
Default is always. Always is means to always overwrite the resource/file, never
means to save the resource/file only if it does not already exist, and only
means to save the resource/file only if it does already exist.

The other set of blocks that can be used is <Var index="#">, like so:
  <Var index="#">
    <Name>...</Name>
    ...
  </Var>

The # must be an integer from 0 to 9 (inclusive).
There may be any number of <Name> blocks.
After this block, whenever a %# (e.g. %1) is used it is replaced with all of the
values defined by the <Name> blocks for that index. There are some limitations
on replacements that can be made. Also %% is replaced by %. For examples, so
the examples zip file.

One very convient thing to do is register BRU files with the BatchResourceUpdater
program so that you can double click the files.
