[Scons-users] how to find dependencies of a given Node?

[David Roundy]

No, the files I want are the graphics files that are required by the tex
file.  Most of them are auto-built, and all of them are found by the scons
scanner, presumably using regular expressions to look for
\includegraphics{file/path}.  One trickery is that the latex file does not
specify the file extension, so the scons scanner has to look at existing
files and existing rules to determine the proper file name to depend upon.
 For the purposes of my tarball, I could assume (as I believe the scons
scanner does) that any non-existing files are pdf files.
