To make trace.tmac handle .nr, .ds, .as, and friends, I've added a new
escape sequence. From groff.texinfo:
-- Escape: \$^
Handle the parameters of a macro as if they were an argument to the
`ds' or similar requests.
.de foo
. tm $1=`\\$1'
. tm $2=`\\$2'
. tm $*=`\\$*'
. tm [EMAIL PROTECTED]@'
. tm $^=`\\$^'
..
.foo " This is a "test"
=> $1=` This is a '
=> $2=`test"'
=> $*=` This is a test"'
=> [EMAIL PROTECTED]" This is a " "test""'
=> $^=`" This is a "test"'
This escape is useful mainly for macro packages like `trace.tmac'
which redefines some requests and macros for debugging purposes.
Enjoy!
Werner
