The purpose of the Common Function Library Project (CFLib.org) is to create a set of user-defined function (UDF) libraries for ColdFusion 5.0 and MX. These libraries are open source and may be used and modified to your liking. Functions range from email format checking to encryption routines. These UDF samples can greatly speed up development time as well as add new and powerful features to your web site.
