Convention for Paths to Product Files

The product described in the present document is designed for operation in different UNIX-based operating system. Real paths to product files depend on the operating system installed on the user’s computer. For notational convenience, the following conventions are used:

•<opt_dir>—directory where main product files are located (including executable files and libraries).

•<etc_dir>—directory where the configuration file and a key file are located.

•<var_dir>—directory where supporting and temporary product files are located.

Real paths corresponding to the conventions in different operating systems are given in the table below.

OS Type	Convention	Real Path
GNU/Linux, Solaris	<opt_dir>	/opt/drweb.com
	<etc_dir>	/etc/opt/drweb.com
	<var_dir>	/var/opt/drweb.com
FreeBSD	<opt_dir>	/usr/local/libexec/drweb.com
	<etc_dir>	/usr/local/etc/drweb.com
	<var_dir>	/var/drweb.com

For space considerations, examples use paths for GNU/Linux operating systems. In some places of the document, where it is possible, examples contain real paths for all of the operating systems.
