# ----- ShellCheck Explanations --------
# SC1090: "at run-time file sourcing" ie '. $pkgfile'
#         We use this to import each package's variables.
# SC2154: "var referenced but not assigned"
#		  All of the config variables are set
#		  at run time when the config is sourced.
# SC2068: for i in $@ ; do : ; done --- loop array splitting
#         This is always done intentionally.
# SC2046 + 2086: Word splitting
#		  This one is the hardest to ignore,
#		  but it is the one most carefully managed.
#		  When words are split, they are done so intentionally.
# SC2119 + SC2120: arguments supplied but not forwarded/used
#		  Shellcheck cannot see arguments given from pkgfiles.
# SC2100: Arithmetic
# 		  Broken in shellcheck. Variables containing '-' cause error.
# SC2153: Possible misspelling
#         Some vars are capital in the config file while lower in the script.
#         Manually manage this.
# SC1092 + SC1091: Cannot source non-existant path
#         Config file paths won't exist when outside the chroot.
# SC2059: Variable in printf strings
#         We use this to print color escape codes in messages.
