# TODO
# (make sure to check for `TODO` within the text of this file if you are updating it, in case something isn't listed here.)    
# - [X] add self-updating (at least version checks and warnings if out of date)
# - [ ] add smart-merging text files
# - [ ] clean up the first lines of this script, taken from a Bullseye 11.6 Debian installation arbitrarily. Assess value & necessity. 
# - [ ] standardize function header comments -- simply document more of the functionality of each addition
# - [ ] add a Glossary to elucidate the additions of this script and how to get started with it.  
# - [X] [MAJOR] create a `~/.zshrc` much like this file, but for (mostly MacOS) `~/.zshrc` users
# ---------------  
#
# CHANGELOG
# 
# v4.5.0
# - added auto-update functionality based on the implemented auto-update functionality in my .zshrc
# 
# v4.4.0
# - retooled for handling of sudo requirements / authorization for silent sourceing whether or not the 
#   executing user is a member of sudo or docker group or not. 
# - moving around some comments such as figfont header
# 
# v4.3.2 - finally added check for `.nvm` directory before sourcing so that nvm doesn't 'need' to be installed to use this .bashrc
# v4.3.1
# - reformatting header
# 
# v4.3.0
# Gonna start keeping an update log here until it gets too long
# - Adding `rmerge` alias for merging with rsync (check alias definition for source attribution)
# - Updating the strategy information in this long comment header
# - Added explanation of functionality of self-updater
# - Updating a lot of function headers
# - Adding TODO items throughout the file
# - Adding TODO section in this header  
# - Better differentiated between default debian ~/.bashrc and my own work 
# 
# v4.2.1
# (this is the version before adding this changelog, but you can check the github commits to see)
