+# This script attempts to determine what APIs exist in the source base that
+# have not been documented. By grepping through all of the doc/*.3 man
+# pages, looking for "Pkg_*" (e.g., Tcl_ or Tk_), and comparing this list
+# against the list of Pkg_ APIs found in the source (e.g., tcl8.1/*/*.[ch])
+# we create six lists:
+# 1) APIs in Source not in Docs.
+# 2) APIs in Docs not in Source.
+# 3) Internal APIs and structs.
+# 4) Misc APIs and structs that we are not documenting.
+# 5) Command APIs (e.g., Tcl_ArrayObjCmd.)
+# 6) Proc pointers (e.g., Tcl_CloseProc.)
+#
+# Note: Each list is "a best guess" approximation. If developers write
+# non-standard code, this script will produce erroneous results. Each
+# list should be carefully checked for accuracy.
