-runcached (Run Cached)
-------------------------------------------------------------------------------
-Execute commands while caching their output for subsequent calls. 
-Command output will be cached for <cacheperiod> seconds and "replayed" for 
-any subsequent calls. Original exit status will also be emulated.
-
-After cacheperiod has expired, command will be re-executed and a new result 
-will be cached. 
-Caching depends on command and arguments executed and the 
-path of the runcached executable. Cache results are stored in /tmp
-
-You can use runcached to run resource-expensive commands multiple times, 
-parsing different parts of its output each time. Those commands will be
-run only once for each cacheperiod. 
-
-Implementation is provided in 3 languages, python, C, BASH.
-
-
-Usage:
-======
-Python:
-runcached.py [-c cacheperiod] <command to execute with args>
-
-C:
-runcached [-c cacheperiod] <command to execute with args>
-
-Bash
-runcached.sh  <command to execute with args>
-
-
-
-Example:
-========
-
-1) Run the date command. Produce a new "date" every 5 seconds.
-runcached.py -c 5 date
-
-2) Zabbix userparameter which can be called multiple times , but actually executes only once every 20 seconds. 
-Query multiple parameters of mysql at the same time, without re-running the query.
-
-UserParameter=mysql.globalstatus[*],/usr/local/bin/runcached.py -c 20 /usr/bin/mysql -ANe \"show global status\"|egrep '$1\b'|awk '{print $ 2}'
