The authors kindly ask that researchers who have used the package cite
references describing it.
INSTALLATION INSTRUCTIONS
In order to run xTerior you need to have first:
1) Mathematica, at least version 9.0 (earlier versions might also work).
2) The xAct software, including xTerior and other packages it needs.
They can all be downloaded as a single file
(the current version is 1.1.2):
Linux/Unix/Mac users:
http://www.xact.es/download/xAct_1.1.2.tgz
Windows users:
http://www.xact.es/download/xAct_1.1.2.zip
The file xAct_1.1.2.tgz (or .zip) must be unpacked in one of the
directories prepared for Mathematica addons. We recommend,
for single-user installations:
Linux/Unix:
$HOME/.Mathematica/Applications/
Windows:
C:\Document and Settings\<user>\Application Data\Mathematica\Applications\
Mac:
/Users/<user>/Library/Mathematica/Applications/
or for system-wide installations:
Linux/Unix:
/usr/share/Mathematica/Applications/
Windows:
C:\Documents and settings\All Users\Application data\Mathematica\Applications\
Mac:
/Library/Mathematica/Applications/
Everything will be placed in a directory xAct under Applications/.
For further installation hints see the "Installation Notes" at the
xAct webpage.
That means that the structure of the essential dependencies should be something like
.../Applications/xAct/xTensor
/xPerm
/xCoba
/Documentation/English/xTeriorDoc.nb
/xTerior/Kernel/init.m
/xTerior.m
/xTerior.nb
At this point, it should be possible to execute everything in the
xTeriorDoc.nb file.
SPECIAL NOTES FOR WINDOWS USERS:
1) The external executable of the xPerm package is required to speed up
the computations. It works for all Mathematica versions under Linux and
Mac, but only for Mathematica 6.0 or higher under Windows.
2) A DOS-like window may appear when loading this executable. Do not
close it; it can be minimized at the task bar.
