142
143 General options:
144 --dir=DIRECTORY Specify the target directory.
145 For --import, this specifies where your
146 configure.ac can be found. Defaults to current
147 directory.
148 --local-dir=DIRECTORY Specify a local override directory where to look
149 up files before looking in gnulib's directory.
150 --verbose Increase verbosity. May be repeated.
151 --quiet Decrease verbosity. May be repeated.
152
153 Options for --import:
154 --lib=LIBRARY Specify the library name. Defaults to 'libgnu'.
155 --source-base=DIRECTORY
156 Directory relative to --dir where source code is
157 placed (default \"lib\").
158 --m4-base=DIRECTORY Directory relative to --dir where *.m4 macros are
159 placed (default \"m4\").
160 --po-base=DIRECTORY Directory relative to --dir where *.po files are
161 placed (default \"po\").
162 --doc-base=DIRECTORY Directory relative to --dir where doc files are
163 placed (default \"doc\").
164 --tests-base=DIRECTORY
165 Directory relative to --dir where unit tests are
166 placed (default \"tests\").
167 --aux-dir=DIRECTORY Directory relative to --dir where auxiliary build
168 tools are placed (default \"build-aux\").
169 --with-tests Include unit tests for the included modules.
170 --avoid=MODULE Avoid including the given MODULE. Useful if you
171 have code that provides equivalent functionality.
172 This option can be repeated.
173 --lgpl Abort if modules aren't available under the LGPL.
174 Also modify license template from GPL to LGPL.
175 --makefile-name=NAME Name of makefile in automake syntax in the
176 source-base and tests-base directories
177 (default \"Makefile.am\").
178 --libtool Use libtool rules.
179 --no-libtool Don't use libtool rules.
180 --macro-prefix=PREFIX Specify the prefix of the macros 'gl_EARLY' and
181 'gl_INIT'. Default is 'gl'.
182 --po-domain=NAME Specify the prefix of the i18n domain. Usually use
183 the package name. A suffix '-gnulib' is appended.
184 --no-changelog don't update or create ChangeLog files
185
186 Options for --import and --update:
187 --dry-run For --import, only print what would have been done.

189 --local-symlink Make symbolic links instead of copying files, only
190 for files from the local override directory.

445 # or when it was built with --enable-usg-echo-default (bash >= 2.0)
446 # or when it was built with DEFAULT_ECHO_TO_USG (bash < 2.0),
447 # - in zsh, when sh-emulation is not set,
448 # - in ksh (e.g. AIX /bin/sh and Solaris /usr/xpg4/bin/sh are ksh instances,
449 # and HP-UX /bin/sh and IRIX /bin/sh behave similarly),
450 # - in Solaris /bin/sh and OSF/1 /bin/sh.
451 # We try the following workarounds:
452 # - for all: respawn using $CONFIG_SHELL if that is set and works.
453 # - for bash >= 2.04: unset the shell option xpg_echo.
454 # - for bash >= 2.0: define echo to a function that uses the printf built-in.
455 # - for bash < 2.0: define echo to a function that uses cat of a here document.
456 # - for zsh: turn sh-emulation on.
457 # - for ksh: alias echo to 'print -r'.
458 # - for ksh: alias echo to a function that uses cat of a here document.
459 # - for Solaris /bin/sh and OSF/1 /bin/sh: respawn using /bin/ksh and rely on
460 # the ksh workaround.
461 # - otherwise: respawn using /bin/sh and rely on the workarounds.
