.SH DESCRIPTION
The
.BR grim
library takes HTML and CSS as a file, string, or virtual document then computes the styles and position for the page.
The output is draw to a canvas, this canvas can share memory with any output. Most commonly this will be to the compositor
of the system OS.

Grim also includes DOM api's from the programming language "JavaScript". This provides a common interface to interact with the
document allowing dynamic updates and user events.

The
.BR llabs ()
function is included since glibc 2.0.
The
.BR imaxabs ()
function is included since glibc 2.1.1.
.PP
For
.BR llabs ()
to be declared, it may be necessary to define
\fB_ISOC99_SOURCE\fP or \fB_ISOC9X_SOURCE\fP (depending on the
version of glibc) before including any standard headers.
.PP
By default,
GCC handles
.BR abs (),
.BR labs (),
and (since GCC 3.0)
.BR llabs ()
and
.BR imaxabs ()
as built-in functions.
