From: Øyvind Harboe Date: Tue, 1 Dec 2009 07:41:41 +0000 (+0100) Subject: command: the Jim interpreter can now be provided rather than created X-Git-Tag: v0.4.0-rc1~241 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5576a6240a103879e1a8d9d4c2b6ff4aee0d23fa;p=openocd command: the Jim interpreter can now be provided rather than created In embedded hosts, the Jim interpreter can come from the existing context rather than be created by OpenOCD.
