Wow, this page is unnecessarily intimidating:

http://www.scala-lang.org/node/212

It would be great if someone could put the most likely to be relevant
links up top - those being scala-2.8.0.latest.* which are presently
about ten screenfuls down.

Assuming you downloaded one of those and unzipped it, there should be a
bin directory in there which contains scala, scalac, etc. You don't
need to mess with jars or anything, just running those from the command
line should be sufficient. I can't contrast this to the cozy
environments as I don't use them.

You can get at the Scala nightly builds from the comfort of Maven too.

Just make sure the repo-snapshots (snapshots, not releases) repository is in your pom.xml:

  <repositories>
    ...
    <repository>
      <id>scala-tools.org</id>
      <name>Scala-Tools Maven2 Repository</name>
      <url>http://scala-tools.org/repo-snapshots</url>
    </repository>
  </repositories>

And then declare a dependency on Scala 2.8.0-SNAPSHOT.

  <properties>
    <scala.version>2.8.0-SNAPSHOT</scala.version>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.scala-lang</groupId>
      <artifactId>scala-library</artifactId>
      <version>${scala.version}</version>
    </dependency>
    ...
  </dependencies>

Once a Maven project is set up with that stuff, you can do 'mvn scala:console' to get a Scala console running 2.8.0-SNAPSHOT or 'mvn scala:run -DmainClass=path.to.my.MainClass' to run a class with a "main" method.

Is there any suitable documentation?

The page is just the prettified form of a directory listing, in which the
results of the nightly builds are unceremoniously dumped. The nightly
builds list is quite appropriately intimidating, I find, as looking at
them should communicate fear and danger.

Jokes aside, the content of the various jars and zips in the nightly
directory is actually the same as the content of the regular distribution.
For example, this tgz:

http://www.scala-lang.org/archives/downloads/distrib/files/nightly/scala...

contains the following:

$ ls -d */*
bin/fsc bin/scalap.bat lib/scalap.jar
bin/fsc.bat doc/LICENSE man/man1
bin/scala doc/README src/scala-compiler-src.jar
bin/scala.bat doc/scala-devel-docs src/scala-dbc-src.jar
bin/scalac lib/scala-compiler.jar src/scala-library-src.jar
bin/scalac.bat lib/scala-dbc.jar src/scala-partest-src.jar
bin/scaladoc lib/scala-library.jar src/scala-swing-src.jar
bin/scaladoc.bat lib/scala-partest.jar src/scalap-src.jar
bin/scalap lib/scala-swing.jar

which is the same as the tgz of the main distribution, as documented at
the page http://www.scala-lang.org/node/36. As Paul observed, just adding
the 'bin' directory to the path, regardless of where the tgz was expanded,
should be sufficient.

FYI, Lift probably won't work with 2.8.0-SNAPSHOT unless you compile Lift from source with 2.8.0-SNAPSHOT.
