\fB\N'45'f\fR, \fB\N'45'\N'45'force\fR

.TP 4
\fB\N'45'\N'45'help\fR[=\fIFMT\fR] (default=auto)
Show this help in format \fIFMT\fR\N'46' The value \fIFMT\fR must be one of `auto\N'39', `pager\N'39', `groff\N'39' or `plain\N'39'\N'46' With `auto\N'39', the format is `pager` or `plain\N'39' whenever the \fBTERM\fR env var is `dumb\N'39' or undefined\N'46'
.TP 4
\fB\N'45'\N'45'libdir\fR=\fIPATH\fR
Directory where library files are copied, relative to \fBprefix\fR or absolute\N'46' If \fB\N'45'\N'45'prefix\fR is specified the default is \fI$prefix/lib\fR, otherwise it is the output of \fBocamlfind printconf destdir\fR
.TP 4
\fB\N'45'\N'45'prefix\fR=\fIPREFIX\fR
Directory where files are copied\N'46' For instance binaries are copied into \fI$prefix/bin\fR, library files into \fI$prefix/lib\fR, etc\N'46'\N'46'\N'46' It defaults to the current opam prefix if opam is available and configured, otherwise it uses the same prefix as the ocaml compiler\N'46'

.P
These options are common to all commands\N'46'
.TP 4
\fB\N'45'\N'45'auto\N'45'promote\fR
Automatically promote files\N'46' This is similar to running \fBdune promote\fR after the build\N'46'
.TP 4
\fB\N'45'\N'45'build\N'45'dir\fR=\fIFILE\fR (absent \fBDUNE_BUILD_DIR\fR env)
Specified build directory\N'46' _build if unspecified
.TP 4
\fB\N'45'\N'45'config\N'45'file\fR=\fIFILE\fR

Debug the findlib sub\N'45'system\N'46'
.TP 4
\fB\N'45'\N'45'default\N'45'target\fR=\fITARGET\fR
Set the default target that when none is specified to \fBdune build\fR\N'46' It defaults to @@default\N'46'
.TP 4
\fB\N'45'\N'45'dev\fR
Same as \fB\N'45'\N'45'profile dev\fR
.TP 4
\fB\N'45'\N'45'diff\N'45'command\fR=\fIVAL\fR
Shell command to use to diff files\N'46' Use \N'45' to disable printing the diff\N'46'
.TP 4
\fB\N'45'\N'45'display\fR=\fIMODE\fR
Control the display mode of Dune\N'46' See \fBdune\N'45'config(5)\fR for more details\N'46'

.TP 4
\fB\N'45'\N'45'no\N'45'buffer\fR
Do not buffer the output of commands executed by dune\N'46' By default dune buffers the output of subcommands, in order to prevent interleaving when multiple commands are executed in parallel\N'46' However, this can be an issue when debugging long running tests\N'46' With \fB\N'45'\N'45'no\N'45'buffer\fR, commands have direct access to the terminal\N'46' Note that as a result their output won\N'39't be captured in the log file\N'46' You should use this option in conjunction with \fB\N'45'j 1\fR, to avoid interleaving\N'46' Additionally you should use \fB\N'45'\N'45'verbose\fR as well, to make sure that commands are printed before they are being executed\N'46'

Ignore stanzas referring to a package that is not in \fBPACKAGES\fR\N'46' \fBPACKAGES\fR is a comma\N'45'separated list of package names\N'46' Note that this has the same effect as deleting the relevant stanzas from jbuild files\N'46' It is mostly meant for releases\N'46' During development, it is likely that what you want instead is to build a particular \fB<package>\N'46'install\fR target\N'46'
.TP 4

.TP 4
\fB\N'45'\N'45'profile\fR=\fIVAL\fR
Select the build profile, for instance \fBdev\fR or \fBrelease\fR\N'46' The default is \fBdev\fR\N'46'
.TP 4
\fB\N'45'\N'45'root\fR=\fIDIR\fR

\fB\N'45'\N'45'workspace\fR=\fIFILE\fR
