==Free/libre software==

We shall use only free/libre software wherever possible. We don't expect to make use of any proprietary software for text processing. However, in rare case of complex raster image processing where free/libre software may not have the requisite equivalent, we might resort to some proprietary software, but will strive hard to get back to free software as soon as the equivalent is available.

The entire [http://www.sayanha.net Sayanha] network, desktops and servers run on GNU/Linux operating system.

==TeX and friends for text processing==

TeX (and its variants like pdfTeX, XeTeX and LuaTeX) is the principal engine for typesetting. We will not use any other typesetting system or proprietary system for the purpose.

==Cloud computing==

==Backup and Continuity Plans==

Apartfrom usual onsite back up, we shall ensure backup in two different continents for the protection of data.

GMD: I would also suggest that to enhance professional standing/perception (e.g., in library community), participation in LOCKSS (http://www.lockss.org/about/what-is-lockss/), for example, should be considered.
