subst - Perform backslash, command, and variable substitutions
subst string
This command performs variable substitutions, command substitutions,
and backslash substitutions on its string argument and
returns the fully-substituted result.
The substitutions are performed in exactly the same way as for
Tcl commands.
As a result, the string argument is actually substituted twice,
once by the Tcl parser in the usual fashion for Tcl commands, and
again by the subst command.
Note: when it performs its substitutions, subst does not
give any special treatment to double quotes or curly braces. For
example, the script
set a 44
subst {xyz {$a}}
returns ``xyz {44}'', not ``xyz {$a}''.
