#	Daily grab comments script..
#
#	This script scans my local mirror for all comment files, and creates and stores a gzipped backup.
#	Then it grabs the latest comments from the live site to the local mirror with sftp.
#
#	Here's the problem:
#
#	The comment file for /so/an/so/index.php and /foo/index.php will both be called "index.php.comment".
#	Clearly, this is going to be a problem when we copy the second comment file into the temporary
#	folder..
#
#	/comm_tmp/index.php.comment /comm_tmp/index.php.comment	Oops!
#
#	The solutionis is to create a parent directories first. now we get:
#
#	/comm_tmp/so/index.php.comment /comm_tmp/foo/index.php.comment
#
#	;o)
#

# get host name..
