texdirflatten – Collect files related to a LaTeX job in a single directory

The Perl script parses a LaTeX file re­cur­sively, scan­ning all child files, and col­lects de­tails of any in­cluded and other data files. Th­ese com­po­nent files, are then all put into a sin­gle di­rec­tory (thus “flat­ten­ing” the doc­u­ment’s di­rec­tory tree).
