 ## Project Structure 
 
-- `el5`: Designed for legacy environments. It requires independent compilation of toolchains (e.g., Perl) to support the build process. 
-- `el6`: Utilizes traditional SysVinit scripts for service startup. 
-- `el7`: Adopts modern Systemd unit files for service management.
