# Usage:
|
|
# generate a choice:
|
|
# gen_choice <out-file> <label> <config-prefix> <base-dir>
|
|
#
|
|
# generate a menuconfig:
|
|
# gen_menu <out-file> <label> <config-prefix> <base-dir>
|
|
#
|
|
# where:
|
|
# out-file
|
|
# put the generated choice/menuconfig into that file
|
|
# for choices, it acts as the base bname of the file, the secondary
|
|
# parts (the .in.2) are put in out-file.2
|
|
#
|
|
# label
|
|
# name for the entries family

# prefix for the choice entries
