autogen

在x86平台上运行不可信任代码的sandbox。

#!/bin/sh

# Most of the kernel and library files come in virtually unchanged.
# Rather than maintain the few changes by hand, we keep a set
# of ed scripts that we can run on the originals to produce 
# the versions we need.
#
# This directory also contains a few files that aren't 
# autogenerated, but are extracted from elsewhere and 
# would distract from vxplan9 itself if placed in the main
# directory (utf.[ch], fmt.[ch], latin1.h, arg.h).
