then able me to swtich between ruby 1.8 and 1.9?
2 important things it does for me are:
1) I make a gemset for every new project or testing with a new Rails
version etc.
So every time, I have a new, clean gem environment (example below)
2) it allows me to install multiple ruby versions, in my _local_
home directory, without
worrying about the version that could be (or maybe not, I don't
care) installed by root
in the central /usr/.. directories.

Example of using rvm gemset : with a new gemset it is really easy to
bootstrap a new Rails
project, without interfering with the existing ones.
<code>
peterv@ASUS:~/data/temp$ rvm use 1.9.3
Using /home/peterv/.rvm/gems/ruby-1.9.3-rc1
peterv@ASUS:~/data/temp$ rvm gemset list
gemsets for ruby-1.9.3-rc1 (found in /home/peterv/.rvm/gems/
ruby-1.9.3-rc1)
contact_app
global
peterv@ASUS:~/data/temp$ rvm gemset create fancy
'fancy' gemset created (/home/peterv/.rvm/gems/ruby-1.9.3-rc1@fancy).
peterv@ASUS:~/data/temp$ rvm use 1.9.3@fancy
Using /home/peterv/.rvm/gems/ruby-1.9.3-rc1 with gemset fancy
You can even streamline this a bit more by putting a .rvmrc file in
your project folder:
/myproject/.rvmrc
rvm_gemset_create_on_use_flag=1
rvm use <rubyversion>@<gemsetname>
RVM will automatically switch to the proper gemset and ruby version as
you "cd" into the project folder (or out of it). There's a lot more
options available in the documentation.
