Appstart should configure automatically the logging frameworks that the 
application can use.
If appstart finds a log4j.properties, or a log4j.xml file in the application 
directory, then it will set the system property
log4j.configuration = <path_to_log4j_config>

If appstart finds a logging.properties file, then it will set the system 
property
java.util.logging.config.file = <path_to_logging.properties>

For Logback library, searches for logback.xml, and sets 
logback.configurationFile property

The values in appstart.properties could be overridden via system properties 
given to the command
java -jar start.jar

for example, to check the output errors of the child process, launch
java -Dapp.follow=true -jar start.jar

What steps will reproduce the problem?
1. Launch appstart with erroneous configuration, i.e. a app.main.class property 
that points to an unexistent class

What is the expected output? What do you see instead?
appstart fails silently, without any visible errors in output. It is expected 
an error log file that logs any exception log

Please use labels and text to provide additional information.
Redirect System.out and System.err in the appstart main to a appstart.log file, 
to be written in ${user.home}

Well, the Xms and Xmx arguments seems to be ignored, I get out of memory error.
If I launch the game from a batch file, with the same xms and xmx values, the 
game runs fine.

app.vm.options=-Xms1g -Xmx1g
app.libs.dir=
#app.class.path=
app.main.class=ui.MainClass
#app.follow=true

Setting app.libs.dir to empty means that the jar file is in the same directory 
as itself.

Allow Appstart to automatically configure native libraries paths, through the 
setting of the system property java.library.path .

The default path for the native libraries shall be 
${app.dir}/nativelib/
|- windows/
|- linux/
|- macosx/
|- solaris/
|- ...

The native library path can be customized, through the setting of the property 
key app.nativelib.dir in the file appstart.properties

add a property to specify a custom JRE to use for launching the desired app.
Note that you need in any case a JRE for launching the appstart.jar !

Test appstart in linux and osx platforms, also with particular configurations

Put a new property in appstart.properties:
app.main.jar = jar_with_main_class.jar

the main class in the manifest.mf file of the specified jar file will be used 
as the main class of the application
