Makefile

# Example commands:
#
#   make
#   make test
#       Runs all tests.
#
#   make test-exe
#       Runs exe regression tests. These use $(gs) and $(mutool) to generate
#       intermediate data about pdf content, then uses $(exe) to convert to
#       docx.
#
#   make test-mutool
#       Runs mutool regression tests. This uses $(mutool) to convert directly
#       from pdf to docx. We require that $(mutool) was built with extract=yes.
#
#   make test-gs
#       Runs gs regression tests. This uses $(gs) to convert directly from pdf
#       to docx. We require that $(gs) was built with --with-extract-dir=... We
#       also do a simple test of output-file-per-page.
#
#   make test-tables
#       Tests handling of tables, using mutool with docx device's html output.
#
#   make test-buffer test-misc test-src
#       Runs unit tests etc.
#
#   make build=debug-opt ...
#       Set build flags.
#
#   make build=memento msqueeze
#       Run memento squeeze test.
