This program makes PNG and/or GIF graphics from DVI files as obtained
from TeX and its relatives.
If GIF support is enabled, GIF output is chosen by using the ‘dvigif’
binary or with the ‘--gif’ option.
It is intended to produce anti-aliased screen-resolution images as fast
as is possible. The target audience is people who need to generate and
regenerate many images again and again. The primary target is the
preview-latex (X)Emacs package, a package to preview formulas from within
(X)Emacs. Yes, you get to see your formulas in the (X)Emacs buffer, see
<http://www.gnu.org/software/auctex/preview-latex.html>.
