Building the timezone files

The building of files is done through the Makefile with:

make clean (important if data files have changed)
make release-pecl (PECL timezonedb extension)
make release-docs (documentation updates)
make release-php (changes to embed database in PHP)

It has the following prerequisites:

The directory contains one tzcode2014i.tar.gz file and one tzdata2014i.tar.gz file.
You have a PECL SVN checkout in ~/dev/php/pecl
You have a PHPDOC GIT checkout in ~/dev/php/phpdoc
You can commit to PHP's GIT php-src repository.
You can commit to PHP's GIT doc-base and doc-en repositories.
You can commit to PECL's SVN repository.
php is in your path.

Do not run this script, unless you're Derick Rethans.
