25 Nov 2009: Some packages removed
Some time ago a new package LofIm was set up, that contains combined and interlinked builds of the packages:
- casacore
- casarest
- pyrap
- LOFAR offline software
- askapsoft (cimager)
The LofIm package is build daily (see lofim for some details). We have stopped building the individual subpackages separately, but the initialization scripts are still there.
To prevent users from activating outdated versions of these subpackages, I will remove the initialization scripts for these, today. All users that want to make use of one of the subpackages, will have to activate the entire LofIm package by typing 'use LofIm' on the command line, or by adding 'LofIm' to your $HOME/.mypackages file (assuming you are using our login scripts).
If a build of LofIm fails, you can revert to an earlier build; see the Wiki page for details.
Let me know of any mishaps or problems you encounter when using the LofIm package, so we can fix things asap, also on behalf of all other users..!
With kind regards,
Arno Schoenmakers
