pushenv
=======

pushenv helps update your Bash or Zsh environment for compilation and
linking with dependencies that are built and installed to different paths.

Installation
------------

    source pushenv.sh

Usage
-----

    pushenv PATH...

Example
-------

Suppose you want to experiment with some C or C++ library whose source
is freely available as a tar ball with an autoconf build system.  You
want the benefits of installing it without the drawbacks of mixing an
experimental library into your standard system paths.

    tar xzf niftywidgets-0.1.2.tgz
    cd niftywidgets-0.1.2
    ./configure --prefix $HOME/local/niftywidgets-0.1.2
    make install

Whenever you want to work with this library, first push compiler,
linker, and man page environment variables into your current
environment.

    pushenv ~/local/niftywidgets-0.1.2

Voila!  Plain old `gcc` and `pkg-config` commands work without hassle
and you can lookup niftywidgets documentation with `man`.
