Replace " wpa_supplicant" with " %wpa_supplicant" except for "struct wpa_supplicant". This makes it easier to write Doxygen comments since there is no need to add the ugly '%' prefix to each instance of wpa_supplicant text showing up.

# This script reads a C source file from stdin, and writes
|
|
# to stdout. Normal usage:
|
|
#
|
|
# $ mv file.c file.c.gtkdoc
|
|
# $ kerneldoc2doxygen.pl <file.c.gtkdoc >file.c
|
|
#
|
|
# Or to do the same thing with multiple files:
|
|
# $ perl -i.gtkdoc kerneldoc2doxygen.pl *.c *.h
|
|
#
|
|
# This script may also be suitable for use as a Doxygen input filter,
|
|
# but that has not been tested.
|
|
#
|
|
# Back up your source files before using this script!!
