This perl-module contains functions that ease updating small text files, usually configuration files. It is easy to write small scripts that can do editing in 'batch mode', a necessary thing when updating *many* hosts at the same time. There is a simple program, update-cfe, that can be used in shell scripts for those who like that. (Sometimes update-cfe is enough to update a section in a file.) As the name suggests, cfe is modelled after the builtin editor in cfengine (a very nice program, but I like perl... :-). And it can only edit files, it can not do all the other stuff that cfengine does.
