Getting Started

===

See the INSTALL document for installation and runtime requirements.

cmogstored aims to be mostly command-line and configuration-file compatible with the Perl mogstored.

cmogstored does not support spawning lighttpd/Apache instances like its Perl counterpart.

In other cases, you can simply replace "mogstored" with "cmogstored" in your init scripts and use the same config file.
