	Converting Linux aic7xxx_seq.c:

	1) generate sequencer code

cp aic7xxx_seq.c seqprog
chmod a+w seqprog
vi seqprog
:1
/{
:1,.d
/}
:.,$d
:%s/[ 	]*0x\(..\), 0x\(..\), 0x\(..\), 0x\(..\),/\U0\4\3\2\1H/
:g/^/j
:g/^/j
:%s/ /, /g
:%s/^/	DD /
:wq


	2) generate patch code

cp aic7xxx_seq.c seqpatches
chmod a+w seqpatches
vi seqpatches
:1
/sequencer_patches
:1,.d
:%s/.*patch\([0-9][0-9]*\)_func\(.*\) }.*/SetPatch(\1 \2);/
	!!! stop here: how many substitutions? -> number of patches !!!
:g/^/j
:g/^/j
:%s/^/	/
:.,$d
:wq

	3) check the patches functions

less aic7xxx_seq.c
