I have installed Sencha Ext JS 5 on OSX Mavericks.
Using ruby 1.9.3 and Java 8u5

When I type in sencha app watch

The code compiles find, however after the last line, it terminates.

Sencha Cmd v5.0.0.116
log4j:WARN No appenders could be found for logger (com.sencha.command.Sencha).
log4j:WARN Please initialize the log4j system properly.
ruby 1.9.3p545 (2014-02-24 revision 45159) [x86_64-darwin13.1.0]
unchanged MyApp-all.scss

If I have to put a log4j.properties file, where will it go?
