Package: lsst
This package sets up a basic environment needed to:
1. install packages from the LSST software server
2. build LSST products from git
3. build external software that uses LSST products
For building products, this package provides the following:
o it sets two useful environment variables that saves typing when
checking out packages from the SVN repository:
+ LSST_GIT The Git repository's base URL, git@git.lsstcorp.org
+ LSST_DMS The base Git URL to the directory containing
LSST products
o it setups up the base package, which is necessary for properly
loading LSST python modules.
For managing products, this package provides the following:
o prepends the address of the LSST software distribution server to
EUPS_PKGROOT environment variable.
DEPRECATED: the package also sets up the following variables, but they're
deprecated and should not be used in future code/scripts.
o sets the LSST_HOME environment variable to the root of the LSST
software stack. This is the directory where the loadLSST scripts
are found.
o sets the LSST_PKGROOT and (if not already set) the EUPS_PKGROOT
environment variables. The latter is used by "eups distrib"
for retrieving and installing new product packages. If
EUPS_PKGROOT is not already set, it is set to the value of
$LSST_PKGROOT
o sets the LSST_PKGS environment variable to the platform-specific
subdirectory of $LSST_HOME where LSST packages are installed.
o if $LSST_DEVEL is set, it is added the the start of the
EUPS_PATH environment variable. $EUPS_PATH has a list of of
colon-delimited directories that EUPS uses to look for software
products to load. A user may set LSST_DEVEL if they want to
install packages but do not have permission to write to
LSST_HOME. By placing it at the front of EUPS_PATH, newly
installed packages will be installed under $LSST_DEVEL.
