#   auto_mkindex
#
# This file provides example cases for testing the Tcl autoloading
# facility.  Things are much more complicated with namespaces and classes.
# The "auto_mkindex" facility can no longer be built on top of a simple
# regular expression parser.  It must recognize constructs like this:
#
#   namespace eval foo {
#       proc test {x y} { ... }
#       namespace eval bar {
#           proc another {args} { ... }
#       }
#   }
#
# Note that procedures and itcl class definitions can be nested inside
# of namespaces.
#

# This shouldn't cause any problems
namespace import -force blt::*

# Should be able to handle "proc" definitions, even if they are
# preceded by white space.

proc normal {x y} {return [expr $x+$y]}
  proc indented {x y} {return [expr $x+$y]}

#
# Should be able to handle proc declarations within namespaces,
# even if they have explicit namespace paths.
