#File Vault Start Up Batch script
#
#Required ENV vars:
#------------------
#  JAVA_HOME - location of a JDK home dir
#
#Optional ENV vars
#-----------------
#  VLT_OPTS - parameters passed to the Java VM when running Vault
#    e.g. to debug vault itself, use
#      set VLT_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
#
# LINE SEPARATOR
# Because it can be pretty tricky to shove a newline character into a batch or shell script and the text "\n" doesn't get
# interpreted as what you might think by Java, vlt will instead look for LF | CRLF in a system property called vlt.line.separator
# and if it exists, it will set the appropriate Java System property accordingly, e.g. -Dvlt.line.separator=LF
