I am not certain why the cvstagdiff was hanging, but I was able to achieve =
the same functionality that I was looking for by using the CVS task and pas=
sing it the "diff" as a command line option.  For example:=0A=0A<cvs dest=
=3D"${cvs.checkout.dir}" output=3D"${cvs.checkout.dir}/out1.txt" error=3D"$=
{cvs.checkout.dir}/out2.txt">=0A  <commandline>=0A    <argument line=3D"dif=
f --brief"/>=0A  </commandline>=0A</cvs>=0A=0AThat is good enough for what =
I am trying to do; plus since I am using the cvs task instead of the exec t=
ask, I am assuming that my ANT script should be platform independent (i.e. =
run on both windows and unix).=0AThanks for your help,=0A-Saladin=0A=0A=0A =
