+This packge contains a modified version of ca-bundle.crt:	
+
+ca-bundle.crt -- Bundle of CA Root Certificates	
+
+Certificate data from Mozilla as of: Thu Nov  3 19:04:19 2011#	
+This is a bundle of X.509 certificates of public Certificate Authorities	
+(CA). These were automatically extracted from Mozilla's root certificates	
+file (certdata.txt).  This file can be found in the mozilla source tree:	
+http://mxr.mozilla.org/mozilla/source/security/nss/lib/ckfw/builtins/certdata.txt?raw=1#	
+It contains the certificates in PEM format and therefore	
+can be directly used with curl / libcurl / php_curl, or with	
+an Apache+mod_ssl webserver for SSL client authentication.	
+Just configure this file as the SSLCACertificateFile.#
