I see that this package also supplies the man page:

~/.local/bin
❯ ls -l pandoc*
-rwxrwxr-x 1 avmo users 74689368 12.06.2019 07:38 pandoc*
-rwxrwxr-x 1 avmo users 61311032 12.06.2019 07:38 pandoc-citeproc*
-rwxrwxr-x 1 avmo users  6511432 25.04.2019 10:09 pandoc-crossref*
-rwxrwxr-x 1 avmo users    30909 25.04.2019 10:12 pandoc-crossref.1*

There is no official advice on how to package man pages, but you can look at:

• https://github.com/nose-devs/nose/blob/master/setup.py#L109
• pypa/packaging-problems/issues/72

It would be really useful to use offline documentation.

Linux and MacOS binaries are packed with upx. This incurs a non-negligible runtime overhead (about 100-300 ms in my tests), but dramatically reduces binary size (up to 10x). If you don't like the overhead, and don't mind 40-megabyte binaries, you can unpack those manually with upx -d pandoc-crossref. This is not done on Windows because for some reason, size reduction is not as dramatic there (only about 50%).

The latest version of pandoc-crossref (and py-pandoc-crossref) that is compatible both with panflute and macOS 10.13 is 0.3.6.2
