libwpd is a library designed to help process WordPerfect documents. It exposes a simple callback-based API (similar to SAX), allowing it to be easily plugged into any C or C++ application. It is used by recent versions of AbiWord and OpenOffice.org to provide WordPerfect file import.
Pathfinder provides a mechanism for any program to perform RFC3280-compliant path validation of X509 certificates, even when some of the intermediate certificates are not present on the local machine. It will automatically download any such certificates and their CRLs from the Internet as needed using the AIA and CRL distribution point extensions of the certificates it is processing. By default, the Pathfinder daemon listens on the D-Bus system bus for incoming requests.
