#       mod_files.sh  - Update of the php-source/ext/session/mod_files.sh
#
# SYNOPSIS
#       mod_files.sh basedir depth [numberofsubdirs]
#
# DESCRIPTION
#       this script creates the directories tree used by php to store the session files
#       (see php.ini - 'session.save_path' option)
#
#       Example: if you want php to store the session files in a directory tree
#       of 3 levels of depth containing 32 directories in each directory,
#       first, put the setting bellow in the php.ini file:
#
#       session.save_path = "3;/tmp/session"
#
#       Now create the basedir directory: 'mkdir /tmp/session'
#
#       Then, call this scrip with the following arguments:
#
#       ./mod_files.sh ./mod_files.sh /tmp/session 3 32
