%# -*-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 `m4_' are processed, and quoting is normal.
%#
%#   2. The preprocessed skeleton is translated into a C array, saved
%#      as "skel.c" and compiled into the flex binary. The %# comment
%#      lines are removed.
%#
%#   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 generated 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.
