******************************
Minimal set of PEAR core files
******************************
This repository provides a set of files from ``pear-core``
that are often used in PEAR packages.
It follows the `pear-core`__ repository and gets updated whenever a new
PEAR version is released.
It's meant to be used as dependency for composer packages.
__ https://github.com/pear/pear-core
==============
Included files
==============
- ``OS/Guess.php``
- ``PEAR.php``
- ``PEAR/Error.php``
- ``PEAR/ErrorStack.php``
- ``System.php``
``PEAR/Error.php`` is a dummy file that only includes ``PEAR.php``,
to make autoloaders work without problems.

/**
* Error Stack Implementation
*
* This is an incredibly simple implementation of a very complex error handling
* facility. It contains the ability
* to track multiple errors from multiple packages simultaneously. In addition,
* it can track errors of many levels, save data along with the error, context
* information such as the exact file, line number, class and function that
* generated the error, and if necessary, it can raise a traditional PEAR_Error.
* It has built-in support for PEAR::Log, to log errors as they occur
*
* Since version 0.2alpha, it is also possible to selectively ignore errors,
* through the use of an error callback, see {@link pushCallback()}
*
* Since version 0.3alpha, it is possible to specify the exception class
* returned from {@link push()}
*
* Since version PEAR1.3.2, ErrorStack no longer instantiates an exception class. This can
* still be done quite handily in an error callback or by manipulating the returned array
