====== How to convert Excel files into PDF ======

It's simple to do using Open Office software -- it have this operation in the main menu File.

And how about to use it on the webserver? -- Very simple. 

Requirements:
  *Linux VPS with about 512Mb RAM
  *HDD from 4Gb
  *OS CentOS 5.2

ToDo:
  -Install XWindows -- 'yum groupinstall "X Window System"'
  -Install VNC-Server
  -Run VNC-Server (geometry 800x600)
  -Connect to it from your home computer using VNC-client
  -Install Firefox -- 'yum install firefox'
  -Using Firefox -- take & install latest OpenOffice
  -Open Calc -- and change its settings into 'Print all sheets'
  -Install ghostscript -- 'yum install gs'
  -Make the new virtual printer using VNC -- 'PDFconverter'
  -Take & install 'pdftk' -- probably it'll help you to modify PDFs

Well. Now you can upload & create a XLS file, then convert it into PDF using command:  \\ 
soffice -norestore -nofirststartwizard -nologo -headless -pt \"PDFconverter\" $fname &

What's it mean? 

  *'soffice' -- is the OpenOffice software 
  *'norestore' -- it'll not ask user about to restore any documents before open the editor
  *'nofirststartwizard' -- no 'Master' window on starting 
  *'nologo' -- no logotype
  *'headless' -- not show any window for user (our user is robot)
  *'pt' -- print the file $fname onto the printer 'PDFconverter'
  *'&' -- run the program in the background mode

That's all for now.
