-# Default locations of userdir and cachedir:
-# (http://wiki.netbeans.org/FaqWhatIsUserdir)
-#
-# On Windows ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
-# with "<AppData>\NetBeans" where <AppData> is user's
-# value of "AppData" key in Windows Registry under
-# "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"
-# and ${DEFAULT_CACHEDIR_ROOT} will be replaced by the launcher
-# with "<Local AppData>\NetBeans\Cache" where <Local AppData> is user's
-# value of "Local AppData" key in Windows Registry under
-# "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders"
-#
-# On Mac ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
-# with "~/Library/Application Support/NetBeans" and
-# ${DEFAULT_CACHEDIR_ROOT} with "~/Library/Caches/NetBeans"
-#
-# On other systems ${DEFAULT_USERDIR_ROOT} will be replaced by the launcher
-# with "~/.netbeans" and ${DEFAULT_CACHEDIR_ROOT} with "~/.cache/netbeans"
-#
-# You can also use ${HOME} variable which will be replaced with
-# user.home JVM system property value. This variable is valid only in
-# netbeans_default_userdir and netbeans_default_cachedir properties.
-#
-# NOTE: If you specify a non-default userdir path on command line
-# (--userdir option) and don't specify a cachedir path (--cachedir option),
-# cachedir will be in "<userdir>/var/cache".
-#
-# Cachedir must be different from userdir. The same cachedir and userdir
-# would cause problems.

-# Options used by NetBeans launcher by default:
-# (can be overridden by explicit command line switches)
-#
-# Note that default -Xmx is selected for you by the JVM automatically.
-# You can find these values in var/log/messages.log file in your userdir.
-# The automatically selected value can be overridden by specifying -J-Xmx
-# here or on the command line.
