.SH NAME
xtwi \- Xilinx Tool Wrapper script for ISE
.\" ------------------------------------------------------------------
.SH SYNOPSIS
.
.SY xtwi 
.OP COMMAND
.YS
.
.\" ------------------------------------------------------------------
.SH DESCRIPTION
The Xilinx ISE setup script redefines PATH and LD_LIBRARY_PATH. The ISE
tools run fine in this environment, but other installed programs on the
system can (and actually do) fail. \fBxtwi\fP helps to keep the ISE 
environment separate from the normal working environment.

The environment variable XTWI_PATH must be setup to the install path 
of the ISE version to be used. Without the /ISE_DS/ which is added
by the ISE installation procedure.

\fBxtwi\fP uses XTWI_PATH to locate the ISE setup script, sources it, 
and execs the \fICOMMAND\fP. This way \fICOMMAND\fP is executed in the
ISE environment, while the login shell stays clean.
