Subject: [ng] automake: new function &almost_verbatim (small refactoring)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d5b52a96cf22911c8d271da9acdef8b4618304e;p=thirdparty%2Fautomake.git

[ng] automake: new function &almost_verbatim (small refactoring)

* automake.in (almost_verbatim): New function, thin wrapper around
'&preprocess_file'.  It requires just the name of the fragment to
preprocess (assuming it is one provided by automake, and thus taking
care to prepend the "$libdir/am/" path and append the ".am" extension
automatically), and then automatically append the processed content
to the '$output_verbatim' global variable.
(handle_all_and_check, handle_install, handle_texinfo): Adjust to use
'&almost_verbatim' instead of '&preprocess_file'.
