USAGE="
papirus-folder-color.sh [OPTIONS]
Generates a user custom icon theme with a different folder color from
the default Papirus blue.
Options:
-h, --help
Show this message.
-c, --color <color>
Choose icon color.
-s, --source_path <path>
Set path to directory holding Papirus theme to be used.
-t, --target_path <path>
Set path to directory where new theme will be generated.
-n, --name <name>
Set name of generated theme.
-l, --link
Symlink icons to source instead of copying.
-d, --dark
Declare theme to be dark and inherit Papirus-Dark.
color must be specified and can be one of:
black,blue,bluegrey,breeze,brown,cyan,deeporange,green,grey,indigo,magenta,nordic,orange,palebrown,paleorange,pink,red,teal,violet,white,yaru,yellow,custom
NB \"custom\" color corresponds to jet black, while \"black\" is actually dark grey.
\"jet-black\" may also be passed as an alias for \"custom\".
If --source_path is not passed, the Papirus theme is read from
/usr/share/icons/Papirus
If --target_path is not passed, the generated theme is written to
~/.local/share/icons/<new theme name>
If --name is not passed, the generated theme will be named
Papirus-${vendor}[-Dark]-<color>.
By default icons will be copied into the new theme, not symlinked.
This increases the size, but improves portability.
Pass --link to generate symlinks instead.
If source_path and target_path are under the same top-level directory
then symlinked icons will use relative paths, otherwise absolute paths.
"

## these can (should, at least for color) be overridden by script options
source_path=/usr/share/icons # place to find source Papirus theme
target_path="$HOME/.local/share/icons" # place to put generated theme
#target_path="$PWD"
copy_files=true # If true, copy icons into new theme instead of symlinking.
