##	The per user domain template for the ftp module.

## <desc>

##	

##	This template allows ftpd to manage files in

##	a user home directory, creating files with the

##	correct type.

##	

##	This template is invoked automatically for each user, and

##	generally does not need to be invoked directly

##	by policy writers.
