source - Evaluate a file as a Tcl script
source fileName
Read file fileName and pass the contents to the Tcl interpreter
as a script to evaluate in the normal fashion. The return
value from source is the return value of the last command executed
from the file. If an error occurs in evaluating the contents of the
file then the source command will return that error.
If a return command is invoked from within the file then the remainder of
the file will be skipped and the source command will return
normally with the result from the return command.
If fileName starts with a tilde, then it is tilde-substituted
as described in the Tcl_TildeSubst manual entry.
