Perl has many builtin functions, and instead of trying to describe them
all, I'll cover their syntax. Refer to other sources for full
documentation.
Perl functions are identified by their unique names (print,chop,close,
etc). For clarity's sake, the function's arguments are supplied as a comma
separated list in parenthesis. The commas are necessary, the parentheses
are often not.

print("length: " ,length("hello world"));
# prints the same thing as
print "length: ",1, length "a";

The latter example hints at perl's beastiness. For our purposes, we'll
always use parenthesis.

Example
For our script, we wan't to save the date the form was filled out more
clearly than the date in the mail headers.

...
$date = `date`;
chop($date);
# begin CGI output
print("Content-type: text/html\n\n");

The first line executes the UNIX command date and puts the output in the
the variable $date. Sine the date has a newline on it, we want to chop
that off. Also, we'll initialize the output of the CGI script - necessary
for successful presentation of the results
