Support for php.ini options
Following the strategy of no longer having to configure php via its .ini-file, we can now add php.ini-options to the xp.ini file.

  == xp.ini ==
  use=~/devel/xp/trunk 
  
  [runtime]
  default=C:/Programme/php-5.2.8-Win32/php
  date.timezone=Europe/Berlin
  ============

The last line is now interpreted as a php.ini option and passed to the runtime (before, it was ignored

).

Additional search paths / RFC #0178
Before, the xp.ini file was looked for in `dirname($0)`/xp.ini. This is still available but additionally the following locations are searched (in the written order) for xp.ini files:

. (current directory)
~/.xp/ (where "~" expands to $HOME, also works on Windows+Cygwin)
Environment.SpecialFolder.LocalApplicationData (only on Windows)
`dirname($0)`/xp.ini (where $0 = filename of the binary)

Merging settings
XP runner settings are controllable by two environment variables, "USE_XP" (same as use=... in the .ini file) and "XP_RT" (same as [runtime]."default" in xp.ini). These variables always have precedence over what is written down in the xp.ini files). To allow inheriting settings though the settings are merged.

E.g.:

  == ~/.xp/xp.ini =======
  use=~/devel/xp/trunk
  ========================
  
  == /opt/xp/bin/xp.ini ==
  [runtime]
  default= C:/Programme/php-5.2.8-Win32/php
  extension=php_mysql.dll
  ========================

This would lead to use_xp being read from the user configuration whereas the runtime and args are selected from the system-wide configuration.

Included XCC
XCC is the XP compiler and used for xp.experiments/arena/lang. The runner is included in the distribution whereas the compiler itself isn't yet. To make it work, add /path/to/devel/xp.forge/trunk/experiments/arena/lang ... to your use_xp setting and you're done

Tests
I've started writing unittests for the XP runners to be able to ensure the Un*x and Windows implementations are consistent.

To install (or update) the XP runners without installing (or updating) the framework, you can use the following:

  $ cd ~/bin
  $ wget 'http://xp-framework.net/downloads/releases/bin/setup' -O - | php
