# Function gathers variables from distributed files among the tree, maps to

# <list> ::= <element> | <element> " " <list>
# <element> ::= <conf-file-name> ":" <map-list>
# <map-list> ::= <mapping> | <mapping> "," <map-list>
# <mapping> ::= <src-var> "-" <dst-var> | <src-var>
#
# We assume no whitespace are allowed between symbols.
# <conf-file-name> is a file holding <src-var> in your system.
# <src-var> is a variable holding value of meaning the same as <dst-var>.
# <dst-var> is a variable which will be set up inside initramfs.
# If <dst-var> has the same name as <src-var> we can omit <dst-var>.

# Example:
# /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
