+%# -*-C-*- vi: set ft=c:
+%# This file is processed in several stages.
+%# Here are the stages, as best as I can describe:
+%#
+%#   1. flex.skl is processed through GNU m4 during the
+%#      pre-compilation stage of flex. Only macros starting
+%#      with `m4preproc_' are processed, and quoting is normal.
+%#
+%#   2. The preprocessed skeleton is translated verbatim into a
+%#      C array, saved as "skel.c" and compiled into the flex binary.
+%#
+%#   3. At runtime, the skeleton is generated and filtered (again)
+%#      through m4. Macros beginning with `m4_' will be processed.
+%#      The quoting is "[[" and "]]" so we don't interfere with
+%#      user code.
+%#
+%# All generate macros for the m4 stage contain the text "m4" or "M4"
+%# in them. This is to distinguish them from CPP macros.
+%# The exception to this rule is YY_G, which is an m4 macro,
+%# but it needs to be remain short because it is used everywhere.
+%#
+/* A lexical scanner generated by flex */
+
+%#  Macros for preproc stage.
+
+%# Macros for runtime processing stage.

+%#
+%# Lines in this skeleton starting with a "%" character are "control lines"
+%# and affect the generation of the scanner. The possible control codes are
+%# listed and processed in misc.c.
+%#
+%#   %#  -  A comment. The current line is omitted from the generated scanner.
+%#   %if-c++-only  -  The following lines are printed for C++ scanners ONLY.
+%#   %if-c-only    -  The following lines are NOT printed for C++ scanners.
+%#   %if-c-or-c++  -  The following lines are printed in BOTH C and C++ scanners.
+%#   %if-reentrant     - Print for reentrant scanners.(push)
+%#   %if-not-reentrant - Print for non-reentrant scanners. (push)
+%#   %if-bison-bridge  - Print for bison-bridge. (push)
+%#   %if-not-bison-bridge  - Print for non-bison-bridge. (push)
+%#   %endif        - pop from the previous if code.
+%#   %%  -  A stop-point, where code is inserted by flex.
+%#          Each stop-point is numbered here and also in the code generator.
+%#          (See gen.c, etc. for details.)
+%#   %not-for-header  -  Begin code that should NOT appear in a ".h" file.
+%#   %ok-for-header   -  %c and %e are used for building a header file.
+%#   %if-tables-serialization
+%#
+%#   All control-lines EXCEPT comment lines ("%#") will be inserted into
+%#   the generated scanner as a C-style comment. This is to aid those who
+%#   edit the skeleton.
