TWiki System Requirements 
Server and client requirements for TWiki 01-Feb-2003
Low client and server requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions.
 Server Requirements 
TWiki is written in Perl 5, uses a number of shell commands, and requires 
RCS (Revision Control System), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.
	
		
			|  Required Server Environment  | 
		
		
			|  Resource  | 
			 Unix  | 
			 Windows*  | 
		
	
	
		
			|  Perl  | 
			 5.005_03 or higher (5.6.1 recommended,   5.8.0 not recommended yet, see TWiki:Codev.UsingPerl58OnRedHat8)  | 
		
		
			|  Non-standard Perl modules  | 
			 Net::SMTP (or sendmail)  | 
			 Net::SMTP, MIME::Base64, Digest::SHA1  | 
		
		
			|  RCS  | 
			 5.7 or higher (including GNU diff)   Optional, but the all-Perl RCS replacement is not currently recommended for live sites - see TWiki:Codev.RcsLite.  | 
		
		
			 GNU diff  | 
			 GNU diff 2.7 or higher is required when not using the all-Perl RcsLite.    Install on PATH if not included with RCS (check version with diff -v)  | 
		
		
			|  Other external programs  | 
			 ls, fgrep, egrep  | 
		
		
			|  Cron/scheduler  | 
			 cron  | 
			 cron equivalents  | 
		
		
			|  Web server  | 
			 Apache 1.3 is well supported; Apache 2.0 is not recommended yet (see TWiki:Support.FailedAuthenticationWithApache2OnWinNT).   For other servers, CGI support, authentication, extended path required  | 
		
	
 * Current documentation mainly covers Linux and Apache installations. See WindowsInstallCookbook?  for a Windows installation guide.  See TWiki:Codev.TWikiOn for help with installation on various platforms including Unix, MacOS X, Apache mod_perl, web hosts, etc.
 Client Requirements 
The TWiki 
standard installation has extremely low browser requirements:
 
-  HTML 3.2 compliant
  -  generates XHTML 1.0 pages that are compatible with HTML 3.2
  -  minimal use of JavaScript in the user interface (degrades gracefully)
  -  no cookies
  -  no CSS
 
 
You can easily add functionality, by customizing 
TWikiTemplates, for one, while tailoring the browser requirements to your situation. 
 Known Issues 
 
-  The TWikiPlugins feature currently does not have compatibility guidelines for developers. Plugins can require just about anything -  browser-specific functions, stylesheets (CSS), Java applets, cookies, specific Perl modules,... - check the individual Plugin specs. 
-  
 Plugins included in the TWiki distribution do not add requirements.
