# We assume no whitespace are allowed between symbols.
# <conf-file-name> is a file holding <src-var> in your system.

# /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
# <list> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
# <element> = /etc/conf.d/keymaps:KEYMAP,extended_keymaps-EXT_KEYMAPS
