<p>Inkscape is an Open Source vector graphics editor, with capabilities

similar to Illustrator, Freehand, CorelDraw, or Xara X using the

open-standard Scalable Vector Graphics (SVG) file format. Inkscape's

main goal is to create a powerful and convenient drawing tool fully

compliant with XML, SVG, and CSS standards.</p>

<p>In contrast to raster (bitmap) graphics editors such as Photoshop or

Gimp, Inkscape stores its graphics in a vector format. Vector graphics

is a resolution-independent description of the actual shapes and

objects that you see in the image. This description is then used to

determine how to plot each line and curve at any resolution or zoom

level.</p>

clients.  Samba is software that can be run on a platform other than

Microsoft Windows. For example, Samba runs on Unix, GNU/Linux, IBM

System z, Solaris, Mac OS X, and OpenVMS, among others. It is

standard on virtually all distributions of GNU/Linux and is commonly

included as a basic system service on other UNIX-based systems as

well. Samba uses the TCP/IP protocol that is installed on the host

server.</p>
