Draco is a script to convert reddit thread to Org document. It accepts a
url & prints the Org document to STDOUT. It'll also print comments along
with their replies.

* Why?
I reference things from the web in my Journal & don't want those links
to break so I save them locally. Previously I used to manually archive
the whole thread, this automates it.
* Demo
This was recorded with =asciinema(1)=.

* News
** v0.3.2 - 2020-11-26
+ Add =author_flair_text= to properties section of each comment.
+ Keep each dot in a single line.
  This feature was added in v0.3.0 but each dot was printed in a new
  line. For huge posts this would be annoying so now dots are printed in
  a single line.
** v0.3.1 - 2020-11-25
Minor improvement.

+ Put author name in code block if it begins & ends with "=_=".
  Org underlines headings that begin & end with "=_=".
** v0.3.0 - 2020-11-24
This version adds code to fetch all the comments in a thread. Now users
can archive the whole thread.

Everyone should get this update, the code has become a lot more complex
since v0.1.3. If you don't want to update then you can get the patches
for small changes from the git history.

+ Fetch all the comments.
+ Add debug message for HTTP calls.
  It'll print a "." for every HTTP call. Users will be able to tell when
  the script is making HTTP calls.
** v0.2.2 - 2020-11-24
This version is mostly structural changes, it'll now be easier to add
code to fetch comments hidden behind "continue this thread".

+ Add more debug information.
** v0.2.1 - 2020-11-24
+ Previously fetching comments hidden under "load more comments" would
  fail if the url passed by user ends in "/". This has been fixed in
  this release.
** v0.2.0 - 2020-11-23
This version makes the script lot more complex. If you download only
small threads then this update is not required.

Previous version (v0.1.3) might throw some errors on threads that have
comments hidden behind "load more comments" but the rest of thread will
be saved.

This version will load all those comments hidden behind "load more
comments". But not those hidden behind "continue this thread". This is a
known bug.

+ Add "[S]" after submitter's comments.
+ Print comments hidden under "load more comments".
+ Document environment variables in manual.
+ Add "limit=500" & "sort=top" to all posts/comments.
+ Print more information when debug is on.
+ Add help option.
