NAME
       dub-dustmite - Create reduced test cases for build errors

SYNOPSIS
       dub dustmite <destination-path> OPTIONS... [-- <application
       arguments...>]

DESCRIPTION
       This command uses the Dustmite utility to isolate the cause of build
       errors in a DUB project.



       It will create a copy of all involved packages and run dustmite on this
       copy, leaving a reduced test case.



       Determining the desired error condition is done by checking the
       compiler/linker status code, as well as their output (stdout and stderr
       combined). If --program-status or --program-regex is given and the
       generated binary is an executable, it will be executed and its output
       will also be incorporated into the final decision.

OPTIONS
       --compiler-status=VALUE
           The expected status code of the compiler run

       --compiler-regex=VALUE
           A regular expression used to match against the compiler output

       --linker-status=VALUE
           The expected status code of the linker run

       --linker-regex=VALUE
           A regular expression used to match against the linker output

       --program-status=VALUE
           The expected status code of the built executable

       --program-regex=VALUE
           A regular expression used to match against the program output

       --test-package=VALUE
           Perform a test run - usually only used internally

       --combined
           Builds multiple packages with one compiler run

       --no-redirect
           Don't redirect stdout/stderr streams of the test command

       --strategy=VALUE
           Set strategy (careful/lookback/pingpong/indepth/inbreadth)

       -j
           Set number of look-ahead processes

       --trace
           Save all attempted reductions to DIR.trace

       -b, --build=VALUE
           Specifies the type of build to perform. Note that setting the
           DFLAGS environment variable will override the build type with
           custom flags.  Possible names:
             debug, plain, release, release-debug, release-nobounds, unittest,
           profile, profile-gc, docs, ddox, cov, cov-ctfe, unittest-cov,
           unittest-cov-ctfe, syntax and custom types

       -c, --config=VALUE
           Builds the specified configuration. Configurations can be defined
           in dub.json

       --override-config=VALUE
           Uses the specified configuration for a certain dependency. Can be
           specified multiple times.  Format: --override-
           config=<dependency>/<config>

       --compiler=VALUE
           Specifies the compiler binary to use (can be a path).  Arbitrary
           pre- and suffixes to the identifiers below are recognized (e.g.
           ldc2 or dmd-2.063) and matched to the proper compiler type:
             dmd, gdc, ldc, gdmd, ldmd

       -a, --arch=VALUE
           Force a different architecture (e.g. x86 or x86_64)

       -d, --debug=VALUE
           Define the specified `debug` version identifier when building - can
           be used multiple times

       --d-version=VALUE
           Define the specified `version` identifier when building - can be
           used multiple times.  Use sparingly, with great power comes great
           responsibility! For commonly used or combined versions and versions
           that dependees should be able to use, create configurations in your
           package.

       --nodeps
           Do not resolve missing dependencies before building

       --build-mode=VALUE
           Specifies the way the compiler and linker are invoked. Valid
           values:
             separate (default), allAtOnce, singleFile

       --single
           Treats the package name as a filename. The file must contain a
           package recipe comment.

       --force-remove
           Deprecated option that does nothing.

       --filter-versions
           [Experimental] Filter version identifiers and debug version
           identifiers to improve build cache efficiency.
