# Bash script to post a local HTML file to a Wallabag instance
#
# This assumes client and user credentials are in a pass(1) entry formatted as
# follows:
#
#   <PASSWORD>
#   login: <USERNAME>
#   client_id: <CLIENT_ID>
#   client_secret: <CLIENT_SECRET>
#
# This can also be cajoled as a (Neo)Mutt filter with, e.g.,
#
#  macro attach,index,pager W "\
#  <pipe-message>~/bin/post_to_wallabag.sh -u $URL<Enter>"\
#        "Post to Wallabag"
#
# This requires a  `:setenv URL ...` before calling the macro, as mutt macros
# don't support interactive input [0].
