+In the example above we used some **''./configure''** options, among them:
+**''%%--with-saxon=saxon-xslt%%''**\\ This is because we have the Debian libsaxon-java package, where the executable is called ''saxon-xslt'' instead of ''saxon''.
+**''%%--enable-svg2png-scaling=16,32,48,96%%''**\\ For each .svg icon, render a png image of the specified size. Images will be named **''icon_XX_YY.png''**.
+**''%%--enable-svg2png-scaling-flag=32,48%%''**\\ Same as above, but only for country flag icons.
 It's time to cross-compile:

+If you need more control files (e.g. a ''postinst'' or alike) you have to tweak with the ''om-make-ipkg'' script.  Here it is the script I use, it looks for the control files into an **''opkg''** directory, so you have to pass just the directory name containing the source tree.

+Control files and other files are arranged into the ''opkg'' directory as needed, here it is an example:
+<code>
+opkg/CONTROL/postinst
+opkg/CONTROL/control
+opkg/etc/rcS.d/S96overcommit_memory.sh
