# Concept study to moderate svgcleaner.  Deposit both this bash script
# and the svgcleaner (with provision of the executable bit), and run
#
# ```shell
# ./dek_optimize_5c.sh
#```
# for a comparison with sibling `dek_optimize_5b.sh`.  Instead of piping
# an intermediate file (stream) across bash anew into the svgcleaner, the
# discovered `--multipass`, the svgcleaner possibly processes the .svg
# until changes of the file size underpass a critical threshold.  Command
# options selected are in the sequence of the now archived documentation of
# the project, see
#
# https://github.com/RazrFalcon/svgcleaner
# https://github.com/RazrFalcon/svgcleaner/blob/master/docs/svgcleaner.adoc
#
# for additional background and typical processing of motifs.
