Synopsis:
   eval <commands>

Description:
   EVAL takes the commands given it and passes them through TekNap's internal
   inline parser before executing them.  This means that variables will be
   expanded once, and the command terminator (;) is honored.  This has the
   same effect as executing a command with INPUT_ALIASES turned on.

Examples:
   To force the display of a variable when not inside an alias:
      eval echo The variable's value is $foo

See Also:
   set(4) input_aliases

Other Notes:
   Care should be taken when using EVAL with untrusted input.  If EVAL
   must be used, it is important to first strip out any characters that
   have special meaning to the inline parser, such as ';'.  Using EVAL in
   this manner can very easily lead to a hijacked client or compromised
   account.
