Hi,
somehow related to that issue, i just gave some tutorials about Sage in
Esfahan (Iran) for a research school about tilings [1]. Since windows was
deployed there, we used the Sage Debian Live USB to run Sage [2]. I was
requested by some participants to install SageManifolds. Here is a way,
open a terminal and type:
cd /opt/sagemath/sage
wget http://sagemanifolds.obspm.fr/spkg/sm-install.sh
chmod +x sm-install.sh
./sm-install.sh
keep dir /opt/sagemath
The last line adds a squashfs layer to the current one(s) so that the
changes related to SageManifolds will remain available for further
reboots. Note that the (compressed) layer takes slightly less than 100M
because the documentation is rebuilt.
If you just want to try SageManifolds without modifying the default Sage
install, it suffice to type the first four lines, so that the changes
won't be kept for next reboot.
Note also that this installation will not be transferred during a clone or
upgrade of the key, since those operations aim at providing an unmodified
version of SDL to the target key.
Ciao,
Thierry
