gEDA-dev: Icarus Verilog command file

[Alan M. Feldstein]

In a command file (the argument to the -c flag) I have

/home/alan/Sun/OpenSPARCT2.1.0beta/design/sys/iop/cpu/rtl/cpu.v
$DV_ROOT/design/sys/iop/ccx/rtl/ccx.v
...

The value of the DV_ROOT environment variable is
/home/alan/Sun/OpenSPARCT2.1.0beta

iverilog doesn't complain about the first Verilog source file, but for 
the second one it reports
$DV_ROOT/design/sys/iop/ccx/rtl/ccx.v: No such file or directory

ccx.v does, in fact, exist.

The iverilog man page claims that "Variables  are substitued in file 
names." Therefore, $DV_ROOT should have been understood, right? Isn't 
that what that means?
