[daisy] PDF book publishing error - Java heap

[Karel Vervaeke]

It depends on how you are running the Daisy wiki:
- Using the provided .bat files
- Using the provided wrapper scripts
- Other, e.g. Tomcat

For Tomcat, again it depends on how you start it.
I believe the most common way is to set the environment variable 
JAVA_OPTS to "-Xmx 512M" for 512M of heap space before running 
$TOMCAT_HOME/bin/catalina.sh start
If you are running tomcat as a windows service, I'm unsure.  Google is 
your friend :)

HTH,
Karel
