Pre-installed development tools in Mac OS X Mountain Lion

I'm convinced that Macs are great for development of all varieties.

Open your terminal for hours of fun, right out of the box.

I don't think any of these are unique to Mountain Lion (10.8), but in my transition from Windows to Mac about a year ago, I was delighted to discover these things came pre-loaded:

• Python 2
  
  $ python
  
• PHP 5
  
  $ php -v
  
• Ruby 1.8.7
  
  $ ruby
  
• SQLite3
  
  $ sqlite3
  
• CUPS (print server; useful for printing to university/corporate print networks)
  
  $ cupsctl
  
  
• OpenSSL
  
  $ openssl
  
• Subversion (I wish it came with git though!)
  
  $ svn
  
  
• libxml
  
  $ xmllint$ xsltproc
  
• Apache server 2.2.22
  
  $ sudo apachectl start    # start the server
  $ sudo apachectl graceful # restarts gracefully
  $ sudo apachectl stop     # stop the server
  
• Java (JRE 6; running these the first time will prompt to install; very easy)
  
  $ java   # run a Java program
  $ javac  # compile a Java program

And since they're essentially Unix-based, Macs have the usual dd, ssh, scp, sed, grep, nano, vi/vim commands.
