+Binman commands and arguments
+=============================
+
+Usage::
+
+    binman [-h] [-B BUILD_DIR] [-D] [-H] [--toolpath TOOLPATH] [-T THREADS]
+        [--test-section-timeout] [-v VERBOSITY] [-V]
+        {build,bintool-docs,entry-docs,ls,extract,replace,test,tool} ...
+
+Binman provides the following commands:
+
+- **build** - build images
+- **bintools-docs** - generate documentation about bintools
+- **entry-docs** - generate documentation about entry types
+- **ls** - list an image
+- **extract** - extract files from an image
+- **replace** - replace one or more entries in an image
+- **test** - run tests
+- **tool** - manage bintools
+
+Options:
+
+-h, --help
+    Show help message and exit
+
+-B BUILD_DIR, --build-dir BUILD_DIR
+    Directory containing the build output
+
+-D, --debug
+    Enabling debugging (provides a full traceback on error)
+
+-H, --full-help

+
+--toolpath TOOLPATH
+    Add a path to the directories containing tools
+
+-T THREADS, --threads THREADS
+    Number of threads to use (0=single-thread). Note that -T0 is useful for
+    debugging since everything runs in one thread.

+-d DT, --dt DT
+    Configuration file (.dtb) to use. This must have a top-level node called
+    `binman`. See `Image description format`_.
+
+-i IMAGE, --image IMAGE
+    Image filename to build (if not specified, build all)
+
+-I INDIR, --indir INDIR
+    Add a path to the list of directories to use for input files. This can be
+    specified multiple times to add more than one path.
+
+-m, --map
+    Output a map file for each image. See `Map files`_.
+
+-M, --allow-missing
+    Allow external blobs and bintools to be missing. See `External blobs`_.
+
+-n, --no-expanded
+    Don't use 'expanded' versions of entries where available; normally 'u-boot'
+    becomes 'u-boot-expanded', for example. See `Expanded entries`_.
+
+-O OUTDIR, --outdir OUTDIR
+    Path to directory to use for intermediate and output files
+
+-p, --preserve
+    Preserve temporary output directory even if option -O is not given

+    Update an ELF file with the output dtb. The argument is a string consisting
+    of four parts, separated by commas. See `Updating an ELF file`_.
+
+-W, --ignore-missing
+    Return success even if there are missing blobs/bintools (requires -M)
+
+Options used only for testing:
+
+--fake-dtb
+    Use fake device tree contents
+
+--fake-ext-blobs
+    Create fake ext blobs with dummy content
+
