.\" The TH Macro is for specifying the title of a new section
.\"
.\" In english:
.\"
.\"   Define the string Ts to be "$1 : $2" where $1 and $2 are the
.\"   first and second args to .TH
.\"
.\" push an "environment" onto the stack so that changes in
.\" font, etc. don't inturrupt what is going on in the
.\" text
.\"
.\" make sure that proportional spacing is on
.\"
.\" print the string Ts, centered
.\"
.\" restore spacing (not covered by environment)
.\"
.\" pop off the enviornment
