The archx.py script takes one or more arguments: each is
an archive number.
Let's call the archive number . The script assumes the
current directory has this structure:
nnn
The image archive directory is subdirectory
“bird-”.
nnn/
The thumbnails live in subdirectory “thumb/”.
The arch- file will be written in subdirectory
“nnn.xmlindices/”.
For example, this command
archx.py 006
would index all the .png files in
bird-006/, produce thumbnails for
them in thumb/, and write its index
to indices/arch-006.xml.
