SYNOPSIS

       ::tcl::build-info ?field?
________________________________________________________________________________________________________________

DESCRIPTION

       This  command  provides  a way to retrieve information about how Tcl was built.  Without any options, the
       command returns the Tcl patchlevel, followed by the '+'-sign, followed by the fossil  commit-id  followed
       by  a  list  of  dot-separated  tags.  If a field is given, this command extracts that field as described
       below. Any other field value not mentioned below will always return "0". For official Tcl  releases,  the
       fields are:

       ::tcl::build-info clang
              Returns the clang version number (as 4 digits) if Tcl is compiled with clang, 0 otherwise.
