+/* This file is not compiled in, it is used only to expose more
+   strings to gettextize.
+
+   Why is this needed?
+
+   Bison emits strings to translate in the generated code, for builtin
+   tokens.  So they appear only in generated parsers, which are not
+   shipped, so they are not in the src tree, so we cannot use them in
+   our POTFILE.
+
+   Except src/parse-gram.c, which is in the source tree.  And even in
+   the git repo.  But to avoid useless diffs in the repo, we do not
+   keep the #line directives in the src tree.  Yet, for the user, we
+   ship a src/parse-gram.c _with_ the #lines.  This is done in a
+   dist-hook which regenerates src/parse-gram.c when we run "make
+   dist".
+
+   Unfortunately, then, update-po traverses the whole tree and sees
+   that the location of the strings to translate in src/parse-gram.c
+   have changed, so the bison.pot is to be updated.  And that is not
+   possible in the "make dist" which is run within "make distcheck"
+   (not the one preparing the dist for distcheck, the one run by
+   distcheck to check that a distributed tarball can build a tarball)
+   because then the src tree is read-only.
+
+   So let's not put src/parse-gram.c in the POTFILE, and expose these
+   strings to gettextize by hand.
