jp (pubsub): new search command: search is a kind of "grep for Pubsub". It's a powerful command which allows to look for specific data in a pubsub node, recurse sub nodes if requested, and execute an action on the result. search allows to look for items with following filter: - simple text search - regex - xpath - python code filters are read an applied in the order in which they appear on the command line. Then flags can be used to modify behaviour, currently there are: - ignore-case to specify if search must be case sensitive or not - invert to invert result of the search (i.e. don't match instead of match) - dot-all which is specific for regex, cf. re module - only-matching which return the matching part instead of the full item Once a item match filters, an action is applied to it, currenlty there are: - print, which do a simple output of the full item (default) - exec, which run a jp command, specifying the service, node and item corresponding to the match - exteral, which run a external command, sending the full item on stdin By default search is only done on requested node, but if max-depth is more than 0, sub nodes will be searched too.

Use this module to temporary store files that need to be integrated to other
projects such as Wokkel.

For example, the changeset that introduced this folder adds RSM (XEP-0059)
support to Wokkel. The files in sat.tmp.wokkel are imported over the initial
wokkel files from sat.plugins.__init__.py
