This document covers any known issues and workarounds for the stated release of
shFlags.
General info
------------
This is both a minor bug fix release, and a minor new feature release of
shFlags. It adds several warning messages, fixes three issues, and now displays
the default value behind the help string when help is requested. Additionally,
the coding standards have been modified slightly and officially documented.
They were taken from the standards used by shUnit2 (the unit testing framework
used for the unit testing).
Please see the CHANGES-1.0.txt file for a complete list of changes.
The unit tests
--------------
shFlags is designed to work on as many environments as possible, but not all
environments are created equal. As such, not all of the unit tests will succeed
on every platform. The unit tests are therefore designed to fail, indicating to
the tester that the supported functionality is not present, but an additional
test is present to verify that shFlags properly caught the limitation and
presented the user with an appropriate error message.
shFlags tries to support both the standard and enhanced versions of **getopt**.
As each responds differently, and not everything is supported on the standard
version, some unit tests will be skipped (i.e. ASSERTS will not be thrown) when
the standard version of **getopt** is detected. The reason being that there is
no point testing for functionality that is positively known not to exist. A
tally of skipped tests will be kept for later reference.

Standard vs Enhanced getopt

Here is a matrix of the supported features of the various **getopt** variants.

|spaces in string options | N | Y |
+-------------------------+---+---+
Known Issues
------------
The **getopt** version provided by default with all versions of Mac OS X (up to
and including 10.5.5) is the standard version. As such, only short flags are
supported.
The **getopt** version provided by default with all versions of Solaris (up to
and including Solaris 10 and OpenSolaris) is the standard version. As such,
only short flags are supported.
Workarounds
-----------
The Zsh shell requires the ``shwordsplit`` option to be set, and the special
``FLAGS_PARENT`` variable must be defined.
