Add important FIXMEs to get rid of command substitution misuse. I have learned that the output of $() is subject to globbing. This is dangerous since we use $() as part of file name generation!
- Improve version output on the terminal and in ENCODEDBY tag: Add version numbers of all used tools which touch the audio data (currently accuraterip-checksum, cuetools, eac-crc, flac and shntool). If bugs are found in the tools, you can check whether your audio files are affected by examining the version numbers. Notice that this requires you to have the latest version of accuraterip-checksum/eac-crc because the previous versions did not support printing the version number.
- Also document the advantage of storing the version numbers in README.md and in the README.txt which perfect-flac-encode generates in the output directory.
- Remove the version numbers from README.txt. This file shall be easy to understand by laymen and we already store versions in ENCODEDBY and in the future perfect-flac-encode.log
