temporary home of some graphics of openbsd syscalls made some some common
applications. 

cat.ps
	graph of the syscalls made by a call to "cat"

configure.ps
	graph of the syscalls done by a ./configure process (for ns, the
	   network simulator)

netscape.ps
	graph of netscape 4.7, visited two sites.

how to generate your own on openbsd:

1. use ktrace to trace the process (flags are for inherited and sysem calls):
	$ ktrace -i -tc cat /tmp/somefile

2. process the ktrace to generate a sequence of the syscalls:
	$ kdump -f ktrace.out | awk '{if ($2 != "ktrace" && $3 ~/CALL/) \
		{print $4}}' | awk -F\( '{print $1}' > cat.calls

3. make the graph using the awk script provided:
	$ ./make_graph.awk cat.calls | sort | uniq > cat.dot

3a. edit cat.dot to fix up the format of the file to dot. specifically, move
	line n-1 to line 1.

4. generate the graph in dot:
	$ dot -Tps -o cat.ps cat.dot
