.SH NAME
Warp \- warp (transform) input dataset
.SH SYNOPSIS
.B astwarp
[\fI\,OPTION\/\fR...] \fI\,ASTRdata\/\fR
.SH DESCRIPTION
Warp is part of GNU Astronomy Utilities 0.8.
Warp will warp/transform the input image using an input coordinate matrix.
Currently it accepts any general projective mapping (which includes affine
mappings as a subset).
.PP
For more information, please run any of the following commands. In particular
the second contains a very comprehensive explanation of Warp's invocation:
expected input(s), output(s), and a full description of all the options.

All options and their values:
$ astwarp \fB\-P\fR
