(Deep breath.) I think ext_copy.py is only half of a pair of scripts.
The other half is a "dummy exporter", something like

fin = open(sys.argv, 'r') # $$i
fout = open(sys.argv, 'w') # $$o
This code could simply be:
import shutils, sys
Thank you for the suggestion José. (I am a rank amateur Pythonist.)
However, testing produced an error until I realised that "import
shutils" should be "import shutil", when it worked perfectly.
To give an example of use: if I want to copy the preview logs back from
the temp directory to the document directory or a subdirectory /LOGS of
it, I define a file format LOG (preview) with extension tmp. The copier is
python -tt $$s/scripts/ext_copy.py -e log -t LOGS $$i $$o
and under converters, from LyX to LOG (preview), enter
python -tt $$s/scripts/dummy_export.py $$i $$o
"Exporting" the current document to LOG (preview) format creates a file
<filename>.tmp in the temp directory (containing a single linefeed
character); ext_copy.py then springs into action and copies the preview
logs back to the /LOGS subdirectory of the document directory. Since I
use the LaTeX runs of the preview mechanism to perform various
non-standard tasks, the logs are often of great interest.
Using these two scripts together like this provides a fairly simple
mechanism for a user to rescue or preserve files from the temp
directory. Perhaps LyX developers might include something like
dummy_export.py, the "other half" of ext_copy.py, with LyX so that this
mechanism is available "out of the box"?
Probably this should be added to trac as to not to be forgotten.
