 Decman functions as a dotfile manager. It will install the defined files, directories and symlinks to their destinations. You can set file permissions, owners as well as define variables that will be substituted in the installed files. Decman keeps track of all files it creates and when a file is no longer present in your source, it will be also removed from its destination. This helps with keeping your system clean. However, decman won't remove directories as they might contain files that weren't created by decman.
