One switch that can help a great deal is -R <section-name>
which can be used if some of your sections don't need to be
loaded (as is frequently the case with proms). Here is its
description:
-R sectionname, --remove-section=sectionname
Remove the named section from the file. This option
may be given more than once. Note that using this
option inappropriately may make the output file
unusable.
Hope that helps a little.
