Transforms (Finish: muuntuu) helper tool.

positional arguments:
  SOURCE_FILE           JSON or YAML source as positional argument
  TARGET_FILE           JSON or YAML target as positional argument

options:
  -h, --help            show this help message and exit
  --source FILE, -s FILE
                        JSON or YAML source
  --target FILE, -t FILE
                        JSON or YAML target
  --debug, -d           work in debug mode (default: False), overwrites any environment variable MUUNTUU_DEBUG value
  --policy-writer POLICY_WRITER
                        [YAML only] select writer policy from (safe, r[ound-]t[rip], or "empty") (default: safe)
  --general-offset GEN_OFFSET
                        general offset (indent) on output (default: 2) - verify the amount yourself, please
  --mapping-offset MAP_OFFSET
                        [YAML only] mapping offset (indent) on output (default: 2) - verify the amount yourself, please
  --sequence-offset SEQ_OFFSET
                        [YAML only] sequence offset (indent) on output (default: 2) - verify the amount yourself, please
  --width WIDTH         [YAML only] constrain width on output (default: 150) - verify the amount yourself, please
  --default-flow-style  [YAML only] select default flow style on output (default: False)
  --sort-base           [YAML only] sort base mapping type on output (default: False)
  --force, -f           overwrite existing targets (default: False)
  --quiet, -q           work in quiet mode (default: False)
  --version, -V         display version and exit

Note: some combinations of writer policy, offsets, and width may lead to invalid YAML as documented in test/fixtures/offsets-width.yaml where the options --general-offset 3 --mapping-offset 1 --policy-writer rt --sequence-offset 2 --width 20 were used when deriving from test/fixtures/offsets-width.yaml:

foo:
 bar:
    - baz
    - quux1 asd asd
   asd adssssssss
    - quux2
