This is the README file for "Alias", the Perl module
that performs aliasing services.
This is Version 2.32.
Perl Version 5.003 or later is required, and you need to be
on a system supported by MakeMaker (which comes with perl) and
a C compiler.
You may find this module useful if you:
* are tired of dereferencing hash-based object attributes
* wish perl could make-do with fewer $, -> and {} things
* are a little scared of using typeglobs
* want the freedom to put what you want, when you want in
the symbol table without having to deal with wierd syntax
* need to use scalar constants in your program since you don't
trust yourself from changing $PI
Most notably, there is an C<attr> function that installs a whole
hash on the symbol table with implicit localization. This allows
you to access object attributes without having to deref the object
everytime, as in most other OO languages.
The other functions are just convenient wrappers for "obscure" perl
functionality.
The C<attr> functionality may belong in the perl core, but I am
making it available as part of this module for folks to see what
it "feels like" to have it first.
It would be interesting to benchmark how much less/more efficient
C<attr> is when compared to regular hash access of object
attributes under various degrees of use.
Comments are always very welcome.

INSTALL
Installation is via the standard mantra.
The distribution assumes you have dynamic linking available. Type
perl Makefile.PL
make
make test
If the tests pass, you can type
make install
to install the module.
Look for newer versions of this module on CPAN. The master site for
CPAN currently is:
ftp://ftp.funet.fi/pub/languages/perl/CPAN
There may be many others closer to your location.
