+# SVC – Service Handling
+
+This framework is a simple tool to handle service starting and restarting.
+
+The documentation is sparse due to it being in alpha stage.
+
+## Installation
+
+ % chmod 755 /bin/svc
+ % cp -rf svc /
+
+## Services
+### Simplest case
+
+ % touch /svc/avail/somebin
+ % svc -s somebin
+
+This will run »somebin« in the $PATH using the script in /svc/bare.sh.
+
+### Some params
+
+ % touch /svc/avail/somebin
+ % echo 'PARAMS="-a"' > /svc/default/somebin
+ % svc -s somebin
+
+This will run »somebin -a« in the $PATH using the script /svc/bare.sh.
+
+### Own script
+
+ % cp /svc/bare.sh /svc/default/somebin
+ % $EDITOR /svc/default/somebin
+ % echo 'SOME_VAR="no"' > /svc/default/somebin
+ % svc -s somebin
+
+This will run »somebin« with the script at /svc/default/somebin using the
+special variable from /svc/default/somebin.
+
+## svc(1)
+
+ % svc -a # list all links in /svc/run (all activated services)
+ % svc -a ser # activate service »ser« to be run on startup
+ % svc -c # create the basic directories of svc (configure)
+ % svc -d ser # deactivate service »ser«
+ % svc -k # kill all services linked to /svc/run
+ % svc -k ser # kill the service »ser«
+ % svc -s # run all services linked to /svc/run
+ % svc -s ser # run service »ser«
+ % svc -l # list all services in /svc/avail
+ % svc -r ser # restart service »ser«
+
+Have fun!
