Sorry, email went out on its own..
I'm currently using CSS 4.5 nightly builds and initially installed
Subverse and Pydev.
When I do a download of the latest build, how can I then update my CSS
without re-installing my 2 plugins?
When you download the nightly build from https://ics-web.sns.ornl.gov/css/nightly,
note that there's also an update repo, https://ics-web.sns.ornl.gov/css/nightly/repo/
So if you downloaded the nightly snapshot 3 weeks ago,
in principle you can run that,
open Help/Install New Software,
either enter a new update site for https://ics-web.sns.ornl.gov/css/nightly/repo/,
or edit the "SNS update site" under "Available Software Sites"
into https://ics-web.sns.ornl.gov/css/nightly/repo/.
If you edit the "SNS update site" to the nightly repo, this will have the advantage or drawback that whenever you start CSS, it might prompt you "There's an update available, do you want to install.." every couple of days unless you disable the automated update check in the preferences.
