<h2>Checking the Current Version</h2>
|
| 12 |
The version of scram you are using can be found with the <p>
|
| 13 |
<pre>
|
| 14 |
scram version
|
| 15 |
</pre>
|
| 16 |
command.
|
| 17 |
<p>
|
| 18 |
<h2>Downloading Alternative SCRAM versions</h2>
|
| 19 |
Once a version of SCRAM has been installed, downloading of other SCRAM versions
|
| 20 |
becomes trivial with the <b>scram version</b> command.
|
| 21 |
<p>
|
| 22 |
If you supply a version number as an argument, SCRAM will check to see if the
|
| 23 |
specified version is already installed. If it isn't then it will attempt to
|
| 24 |
download the requested version automatically.
|
| 25 |
<p>
|
| 26 |
e.g.
|
| 27 |
<pre>
|
| 28 |
scram version V0_9_11
|
| 29 |
</pre>
|
| 30 |
<p>
|
| 31 |
<h2>Using Multiple SCRAM versions</h2>
|
| 32 |
<h3>Making a version the default</h3>
|
| 33 |
Running the <em>install_scram</em> script of a specific version
|
| 34 |
(see <a href=install.html>Installation Guide</a>)
|
| 35 |
will make that version the default.<p>
|
| 36 |
<h3>Overriding the default Version</h3>
|
| 37 |
The default version can be overridden at any time by setting the
|
| 38 |
<b>SCRAM_HOME</b> environmental variable to point to the top of the version
|
| 39 |
required. It must be the full path to the version.
