# == About ==
#
# I call pagenav the stuff directly below the first h1. These include file dates
# and GitLab source link.
# Currently it only works for blog and tutorial pages.
#
# This is by far the most hard-coded and inefficient awk script in awk-edits.
# Creation and last edited dates are taken from git commits, and getting the correct info
# by file name can only be done (easily) with git log, which is unfortunately very slow.
# Another issue is that it depends on the build directories in build scripts, meaning
# it won't work without modification if you try to build it somewhere else.
#
# Split into Pagenav.awk and post-pagenav.awk
