The Results of the Band Details Alteration Request

If the web-server does not # has 'write' permission the script does not complain but the # target file is not updated. # # Ideas: # make the date a better format, check to see if the file # is writable, etc. # Dependencies: # plaintext2html-forum.sh # # See Also: # There are some cgi scripts which are similar to this # add-comment, check-hotmail # Author: # mjb # The line below parses the querystring or posted environment # variables. It uses a program which was found at. # http://www.fpx.de/fp/Software/ProcCGIsh.html # eval "`./procgi $*`" echo "Content-type: text/html" echo "" # This second empty echo line IS necessary.
