Abbreviation of a caption

Hello,

Perhaps s.o. can help me.
I am writing a Software-Cookbook and I have very long headings.
Unfortunately it is not possible to make them shorter without loosing
the sence. Now, they do not fit into the caption that is generated
automatically (output: PDF). Thus, I have one line less and my text
reaches into the header. That does not look very nice in the generated
PDF.
I heard that it is possible to abbreviate the header. How does this
work?

Regards,
Yvonne
