# FILE: replace_derived

# USAGE: ./replace_derived show_number
|

#
|
||||
# DESCRIPTION: Given a show that has already been uploaded to the IA, upload
|
||||
# a locally derived set of files to replace those generated by
|
||||
# the IA themselves. The IA's process of deriving files does not
|
||||
# propagate the tags, which we really want to do.

Usage: ./${SCRIPT} show_number

For a show already on the archive it determines if the files are those derived
|
||||
by the IA software and if not collects the WAV file (if necessary) and
|
||||
generates all the derivatives (if necessary), then it uploads these
|
||||
replacements. This is necessary because the IA's derivation process does not
|
||||
copy the audio tags across to the derived files whereas we do.
