****************************************
INSTALLATION NOTES FOR THE xPand PACKAGE
****************************************
General Information:
*********************
Visit http://www2.iap.fr/users/pitrou/xpand.htm
In order to install xPand, you first need to install xAct.
Installation of xAct:
*********************
Download the latest the xAct package on 'http://www.xact.es/download.html'. Install instructions are provided on this website.
Once xAct is installed correctly, it should be located in one of the places that
Mathematica prepares for external applications:
Linux:
- system-wide installation (requires root priviledges):
/usr/share/Mathematica/Applications/
or
/usr/local/Wolfram/Mathematica/9.0/AddOns/Applications/
- single-user installation:
$HOME/.Mathematica/Applications/
Mac OS:
- system-wide installation (requires root priviledges):
/Library/Mathematica/Applications/
or
/Applications/Mathematica 9.0.app/AddOns/Applications/
- single-user installation:
/Users/<user>/Library/Mathematica/Applications/
MSWindows:
- system-wide installation:
C:\Documents and settings\All Users\Application data\Mathematica\Applications\
or
C:\Program Files\Wolfram Research\Mathematica\9.0\AddOns\Applications\
- single-user installation:
C:\Documents and settings\<user>\Application Data\Mathematica\Applications\
Beware that in Windows these directories might be hidden!
Installation of xPand:
**********************
The package can be downloaded as a single tarball xPand_0.4.2.tar.gz.
When uncompressed (typing 'tar -xzvf xPand_0.4.2.tar.gz' under Linux),
it gives
-a folder 'xPand'
-this documentation file 'documentation_xpand.txt''
Note that in some cases, for instance if you uncompress the tarball by a double
click, these 2 items are likely to be placed below a folder named xPand_0.4.2.
The folder 'xPand' must be placed inside the
xAct directory. For instance, in a single user installation with Mac
OS, there should be a folder
/Users/<user>/Library/Mathematica/Applications/xAct/xPand
Documentation:
**************
To load the CMB documentation go to `Add-Ons and Packages' in the Documentation
Center (versions 6.0 of Mathematica at least required), then in 'xAct
Packages' and 'xPand'.
Then the package can be loaded using unix style
Needs["`xAct`xPand"]
or Mathematica style
<<xAct`xPand`
If you encounter any problem, don't hesitate to contact me at
pitrou@iap.fr
This is the "install" file of xPand. Last update: 11 Nov 2013.
