+# This page is for maintenance of the lists of CPP symbols that are eventually
+# included in error.c (‘errno’ values: E*) and posix.c (signal names: SIG*),
+# in the funcs scm_init_{error,posix}, respectively.
+#
+# The lists (files cpp-{E,SIG}.syms) are not included verbatim, but processed
+# (via pattern rule ‘.syms.c’ below) so that each CPP symbol is transformed to
+# fragment of #ifdef'd C code that defines a Scheme variable of the same name.
+# The resulting files, cpp-{E,SIG}.c, are the ones #include:d.
+#
+# To maintain the (source) lists of symbols, we use a GCC-specific feature
+# to list all symbols #define:d when expanding <{errno,signal}.h>, grep
+# the output for {E,SIG}*, massage the result into a usable form, and
+# construct a union of the current and new symbols. This is written to
+# files cpp-{E,SIG}.syms.NEW for review. If things look ok, you can then
+# "mv foo.NEW foo" and commit. Generating the foo.NEW files and showing
+# an informative message is the job of targets chknew-{E,SIG}.
+
+# For each line in foo.syms, transform:
+# SYMBOL
+# to:
+# #ifdef SYMBOL
+# scm_c_define ("SYMBOL", scm_from_int (SYMBOL));
+# #endif
+# writing output to foo.c.
