Help publishing a website

I have puzzled with this off and on for a while, but I think I am going 
to have to ask the experts now.  I am having trouble publishing my 
website with aap.  It seems to build everything okay, but when I do a 
publish, some directory names are being ignored, so most things are 
getting dumped into the main directory instead of the specified 
subdirectory.

I have attached a representative sample of what I am doing.  I tried to 
model my setup after what is in the documentation, but appear to have 
missed something.  Basically, my main.aap does

###
FTPROOT=file:~dwsharp/temp

:child ftplugin/main.aap

FILES = index.html
         images/vim.moolenaar.vimlogo.png
         ftplugin/$*FTPLUGIN_FILES

:attr {publish = $FTPROOT/%file%} $FILES

all: $FILES
         :print $FILES
###

and the ftplugin/main.aap (attached here as ftplugin-main.aap) does

###
LIST_FILES = *.vim

:include ../common.aap

_top.FTPLUGIN_FILES = index.html
                       $LIST_FILES

all: $_top.FTPLUGIN_FILES
###

I thought a publish would create a tree like
/home/dwsharp/temp/index.html
/home/dwsharp/temp/images/vim.moolenaar.vimlogo.png
/home/dwsharp/temp/ftplugin/index.html
/home/dwsharp/temp/ftplugin/ant.vim
/home/dwsharp/temp/ftplugin/aspvbs.vim
...

but instead I end up with
/home/dwsharp/temp/index.html
/home/dwsharp/temp/images/vim.moolenaar.vimlogo.png
/home/dwsharp/temp/ant.vim
/home/dwsharp/temp/aspvbs.vim
...

so specifying 'images/vim.moolenaar.vimlogo.png' successfully creates 
the subdirectory, but 'ftplugin/$*FTPLUGIN_FILES' does not.

Also, the ':print $FILES' command in main.aap correctly shows the list 
of files as 'index.html images/vim.moolenaar.vimlogo.png 
ftplugin/index.html ftplugin/*.vim' but a verbose publish never shows 
ftplugin/index.html being copied, and the index.html I end up with is 
the one for the main directory (which is correct, but means that the 
ftplugin/index.html is not being touched at all in the publish; 
otherwise, I would have expected it to overwrite the main one).

If anyone has some ideas and suggestions, I would love to hear them. 
One thing I did notice is that the verbose publish shows

Aap: Copied "images/vim.moolenaar.vimlogo.png" to 
"file:~dwsharp/temp/images/vim.moolenaar.vimlogo.png"
Aap: Copied "ftplugin/ant.vim" to "file:~dwsharp/temp/ant.vim"

Is there something extra that needs to be done when declaring a path 
with a variable vs. a harcoded path?
