+# This program looks for texinfo snippets in source files and other
+# files, and builds per-category files with entries sorted in
+# alphabetical order.
+
+# The syntax it looks for is lines starting with '@def' in *.c and
+# other files (see TEXIFILES in Makefile.in).  Entries are terminated
+# at the next @def* (which begins a new entry) or, for C files, a line
+# that begins with '*/' without leading spaces (this assumes that the
+# texinfo snippet is within a C-style /* */ comment).
