# Obviously this should be in a [decompress] section or such, but it was
# once forgotten and remained global for compatibility. The first word
# 'uncompress' should have been the section name and has no other meaning.
#
# The second word is the name of a script or program to execute to
# produce an uncompressed copy (e.g.: rcluncomp). It must output the
# uncompressed file name on stdout, and produce no data out of the
# temporary directory given as parameter. The uncompressed file name should
# preserve the original file extension (i.e. use gunzip myfile.doc.gz not
# gunzip < myfile.doc.gz > myfile.whateverwrongextension)
#
# The %t parameter will be substituted to the name of a temporary directory
# by recoll. This directory is guaranteed empty when calling the filter

# The %f parameter will be substituted with the input file.

# The script (ie: rcluncomp) must output the uncompressed file name on
# stdout.
# Note that it should be possible to improve performance a lot by writing a
# compressor-specific script instead of the generic rcluncomp which will
# copy the compressed file into the temporary directory as a first step in
# all cases.
