A method to grab the comments from YouTube videos

• Requires qwarc and realpath from GNU coreutils 8.23+.
• Execute as comments VIDEOID where VIDEOID is the 11-character video ID from YouTube.
• You can pass multiple video IDs at once as well: comments VIDEOID1 VIDEOID2 .... They get executed sequentially.
• Comments are grabbed only in the ‘newest first’ order, including replies and nesting.
• Everything’s written to a few files in the current directory called youtube-comments-VIDEOID-DATE*.
• After the retrieval finished cleanly and you’re satisfied with the results, you can delete the .db and .log files. The former is essentially useless, and the latter is contained in the -meta.warc.gz file.
