#### ZSHRC - Setting up the Shell
## 
## Almost all actual setup is being done with the help of individual files 
## in the .zsh.d/ directory. They follow a specific order:
##
## 00-09 are bootstrapping the zsh environment, setting aliases and sane
##       shell defaults which should need no changes
## 10-19 allow custom bootstrapping of things that need to be set before any
##       zsh plugins are loaded (in my case, theme environment vars, etc)
## 20-29 are run *during* zgen setup and can include plugins to be loaded
## 30-99 are run after plugins are loaded and can be configured 
##       in whatever way you wish
##
## Most of them are documented, and they try to have sensible naming. 
## If you want to supply your own directory of zsh config files you can do so 
## by setting the ZSH_CONFIG_DIR environment variable. You can also drop 
## configuration files into the config dir without any numbers prepended, they
## will be run after numbered ones (in a random order) if you uncomment the 
## corresponding line below.
