.SH NAME
concat_affine \- Concatenate affine transformations
.SH SYNOPSIS
concat_affine [options] x0 [x1 ...] 
 WHERE x0 ... xN is [{-i,--inverse}] affine transformation #. (If the first transformation in the sequence is inverted, then '--inverse' must be preceded by '--', i.e., use '-- --inverse xform.path').
.SH DESCRIPTION
This tool computes the explicit concatenation of multiple affine coordinate transformations, each of which can be optionally inverted.
