| ## Conventional UNIX Directories Some files and directories used by DCE are accessible in conventional UNIX directories. These DCE files and directories need to be accessible in conventional locations so users can conveniently access frequently used utilities and data, such as idl from the /usr/bin directory and localtime from the /etc/zoneinfo directory. Header files are accessible in /usr/include or in its subdirectory, /usr/include/dce, and libraries, such as libdce.a, are kept in /usr/lib. ##
