### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. 
###.   Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of 
###.   things to watch out for:
###      - Check out the `nix-darwin` instructions, as they have changed.
###      - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.

Email message parsing in Haskell in 2018

Background: I am moving away from GMail to my own Haskell-based server (SMTP receiver/sender, web-based email client, spam filtering, etc.). All email to @chrisdone.com goes through this server (mx.chrisdone.com) as of today, and chrisdone@gmail.com forwards a copy of everything to it.

This is a summary/tracking document of my efforts to simply parse email messages in Haskell for the SMTP receiver.

# This script, executed at the root of a git repository, deletes traces of every old file in this repository, index + blob on all branches
# It can take 10-30 minutes to run and will print regular warning stating than some references are unchanged
# time ./clear_git_repositor.bash >cleaning.log 

# We need several passes to clean files renamed multiple times (git log --find-renames prevents its deletion for each renaming)
# MAXIMUM_PASSES should be more than the maximum number of renamings/movings for any file, if not then we might keep some traces of former files
