print "Content-Type: text/html \n\n";
print "Welcome to ACME AUTO";
This print command tells the Web server to “print” a line of text to a Web browser.
Content-Type: text/html tells the web browser that what comes next is HTML, or text that can be read by a Web browser.
The \n character tells the Web browser to print the HTML code that follows on a new line.
Since there are two new lines specified, a blank line is printed between this line of code and the next.
