Both apps/webbrowser and apps/webserver contain a http-strings.c. It seems unclear to me if the original intention was to have them identical (but then they should have been factored out in the first place) or if they were only very similiar by chance.
Anyway, currently webserver/http-strings.c is a clean superset of webbrowser/http-strings.c so if a project has both HTTP server and client parts it is desirable to use the webserver variant. In the case of apps/shell this can be archived by adding webserver *before* webbrowser to the APPS variable.
This seems like a hack to me - but the whole shell build qualifies as hack, doesn't it ;-)
performance between two local (single-hop) nodes. It sends packets
over both broadcast and unicast, both in one direction and in both, as
well as tested the stream mode of the underlying MAC protocol.
insertion of new commands and command pipelining. There are also a
bunch of new commands for network access (using Rime): ping, data
collection, packet sniffing, sending shell commands across the
network, and testing the single-hop throughput to neighboring
nodes. Commands are also available for reading from and writing to
files, reading the sensors (on the Tmote Sky platform), and accessing
the power and energy consumption of the system. Dynamic loading of
programs across the network is also possible, although a little
untested at the moment.
