c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	4	Normally, when distributions are installed, if any processing is
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	5	needed, they are downloaded from the internet to a temporary directory
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	6	and then installed from there. A download cache can be used to avoid
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	7	the download step. This can be useful to reduce network access and to
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	8	create source distributions of an entire buildout.
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	9
c6bca38c1cbf Added buildout stuff and made changes accordingly Nishanth Amuluru <nishanth@fossee.in> parents: diff changeset	10	The buildout download-cache option can be used to specify a directory
