 %# 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.
 m4preproc_changecom
 %# Macros for runtime processing stage.
 m4_changecom
 m4_changequote
 m4_changequote([[, ]])
 %#
 %# 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.
