+
+Sign all FILES, and process them at selected destinations according to CMD.
+<http://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+explains further.
+
+Commands:
+ --delete delete FILES from destination
+ --symlink create symbolic links
+ --rmsymlink remove symbolic links
+ -- treat the remaining arguments as files to upload
+
+Options:
+ --help print this help text and exit
+ --to DEST specify one destination for FILES
+ (multiple --to options are allowed)
+ --user NAME sign with key NAME
+ --symlink-regex[=EXPR] use sed script EXPR to compute symbolic link names
+ --dry-run do nothing, show what would have been done
+ --version output version information and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with \`-latest', e.g.:
+
+ foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+ alpha.gnu.org:DIRECTORY
+ savannah.gnu.org:DIRECTORY
+ savannah.nongnu.org:DIRECTORY
+ ftp.gnu.org:DIRECTORY
+ build directive files and upload files by FTP
+ download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+ build directive files and upload files by SFTP
+ [user@]host:DIRECTORY upload files with scp
+
+Options and commands are applied in order. If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options. Use this to keep your defaults. Comments
+(#) and empty lines in $conffile are allowed.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink-regex \\
+ foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Upload foobar-0.9.90.tar.gz to two sites:
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ foobar-0.9.90.tar.gz
+
+5. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+ (the -- terminates the list of files to delete):
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ --delete oopsbar-0.9.91.tar.gz \\
+ -- foobar-0.9.91.tar.gz
+
+gnupload uses the ncftpput program to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(http://savannah.gnu.org/projects/gnulib) may serve as a replacement.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ This macro is useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead. However, one of the reasons that a function is a
+ portability trap is if it has the wrong signature. Declaring
+ FUNCTION with a different signature in C is a compilation error, so
+ this macro must use the same type as any existing declaration so
+ that programs that avoid the problematic FUNCTION do not fail to
+ compile merely because they included a header that poisoned the
+ function. But this implies that _GL_WARN_ON_USE is only safe to
+ use if FUNCTION is known to already have a declaration. Use of
+ this macro implies that there must not be any other macro hiding
+ the declaration of FUNCTION; but undefining FUNCTION first is part
+ of the poisoning process anyway (although for symbols that are
+ provided only via a macro, the result is a compilation error rather
+ than a warning containing "literal string"). Also note that in
+ C++, it is only safe to use if FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+ [getline]) in configure.ac, which potentially defines
+ HAVE_RAW_DECL_GETLINE
+ - adding this code to a header that wraps the system <stdio.h>:
+ #undef getline
+ #if HAVE_RAW_DECL_GETLINE
+ _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+ "not universally present; use the gnulib module getline");
+ #endif
+
+ It is not possible to directly poison global variables. But it is
+ possible to write a wrapper accessor function, and poison that
+ (less common usage, like &environ, will cause a compilation error
+ rather than issue the nice warning, but the end result of informing
+ the developer about their portability problem is still achieved):
+ #if HAVE_RAW_DECL_ENVIRON
+ static inline char ***rpl_environ (void) { return &environ; }
+ _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
