# simplistic server side gatekeeper script
#
# periodically poll a certain directory ("FAX_IN_DIR"). If there is any
# file present, take all digits from the filename, and pass that plus
# the file itself to faxspool(1)
#
# so a file "fax-12345.pdf" would result in "faxspool 12345 fax-12345.pdf"
# being called. Use "faxspool.rules" to ensure that faxspool knows how
# to convert the document formats your users drop there...
#
# afterwards, send a mail to the owner of the file that the job was
# queued, and move the file to "FAX_ARCH_DIR", unless empty - in that
# case, delete
#
# to be run from root's crontab
