First, get a newer version from Daisuke Aoyama's home page (the address 
should be in the README files).  Many bugs have been fixed since the 
initial release.

Second, to debug a shell script, put a line like this at the beginning of 
the script:

	set -x

I suggest you run such scripts with redirected stdout and stderr, or 
catch them with an editor that can compile from within it.

Third, install the following packages, and many of the problems will go 
away:
	- Make 3.75
	- fileutils
	- textutils
	- sh-utils
	- grep
	- sed
	- gawk
	- diffutils

Also, make a ``symlink'' to bash.exe called sh.exe and a ``symlink'' to 
gawk.exe called awk.exe:

		ln -s bash.exe sh.exe
		ln -s gawk.exe awk.exe

(`ln' is part of fileutils).
