+.SH DESCRIPTION
+\fByanglint\fP is a command-line tool for validating and converting YANG
+schemas and the YANG modeled data. For a simple use, it validates the provided
+file and if the output format specified, it converts input data into the output
+format. If started with no argument, \fByanglint\fP opens interactive
+environment where the user is allowed to work with schemas and data in a more
+complex way.
+.
+.SH OPTIONS
+.TP
+.BR "\-h\fR,\fP \-\^\-help"
+Outputs usage help and exits.
+.TP
+.BR "\-v\fR,\fP \-\^\-version"
+Outputs the version number and exits.
+.TP
+.BR "\-V\fR,\fP \-\^\-verbose"
+Increases the verbosity level. If not specified, only errors are printed, with
+each appearance it adds: warnings, verbose messages, debug messages (if compiled
+with debug information).
+.TP
+.BR "\-p \fIPATH\fP\fR,\fP \-\^\-path=\fIPATH\fP"
+Specifies search path for getting imported modules or included submodules. The option
+can be used multiple times. The current working directory and path of the module
+being added is used implicitly.
+.TP
+.BR "\-s\fR,\fP \-\^\-strict"
+Changes handling of unknown data nodes - instead of silently ignoring unknown data,
+error is printed and data parsing fails. This option applies only on data parsing.
+.TP
+.BR "\-f \fIFORMAT\fP\fR,\fP \-\^\-format=\fIFORMAT\fP"
+Converts the content of the input \fIFILE\fPs into the specified \fIFORMAT\fP. If no
+\fIOUTFILE\fP is specified, the data are printed on the standard output. Only the
+compatible formats for the input \fIFILE\fPs are allowed, see the section \fBFORMATS\fP.
+.TP
+.BR "\-o \fIOUTFILE\fP\fR,\fP \-\^\-output=\fIOUTFILE\fP"
+Writes the output data into the specified \fIOUTFILE\fP. The option can be used
+only in combination with \fB--format\fR option. In case of converting schema, only
+a single input schema \fIFILE\fP is allowed. In case of data input \fIFILE\fPs,
+input is merged and printed into a single \fIOUTFILE\fP.
+.TP
+.BR "\-F \fIFEATURES\fP\fR,\fP \-\^\-features=\fIFEATURES\fP"
+Specifies the list of enabled features in the format
+\fIMODULE\fP:[\fIFEATURE\fP,...]. In case of processing multiple modules, the
+option can be used repeatedly. To disable all the features, use an empty list
+specified for the particular module.
+.TP
+.BR "\-d \fIMODE\fP\fR,\fP \-\^\-default=\fIMODE\fP"
+Print data with default values, according to the \fIMODE\fP (to print attributes,
+the ietf-netconf-with-defaults model must be loaded). The \fIMODE\fP is one of the following:
+ \[bu] \fBall\fP             - add missing default nodes
+ \[bu] \fBall-tagged\fP      - add missing default nodes and mark all the default nodes with the attribute
+ \[bu] \fBtrim\fP            - remove all nodes with a default value
+ \[bu] \fBimplicit-tagged\fP - add missing nodes and mark them with the attribute
+.TP
+.BR "\-t \fITYPE\fP\fR,\fP \-\^\-type=\fITYPE\fP"
+Specify data tree type in the input data \fIFILE\fPs. The \fITYPE\fP is one of the following:
+ \[bu] \fBauto\fP            - Resolve data type (one of the following) automatically (as pyang does). Applicable only on XML input data.
+ \[bu] \fBdata\fP            - Complete datastore with status data (default type).
+ \[bu] \fBconfig\fP          - Configuration datastore (without status data).
+ \[bu] \fBget\fP             - Result of the NETCONF <get> operation.
+ \[bu] \fBgetconfig\fP       - Result of the NETCONF <get-config> operation.
+ \[bu] \fBedit\fP            - Content of the NETCONF <edit-config> operation.
+ \[bu] \fBrpc\fP             - Content of the NETCONF <rpc> message, defined as YANG's rpc input statement.
+ \[bu] \fBrpcreply\fP        - Reply to the RPC. This is just a virtual \fITYPE\fP, for parsing replies, '\fBauto\fP' must be used since the data \fIFILE\fPs are expected in pairs.
+.br
+                     The first input data \fIFILE\fP is expected as '\fBrpc\fP' \fITYPE\fP, the second \fIFILE\fP is expected as reply to the previous RPC.
+ \[bu] \fBnotif\fP           - Notification instance (content of the <notification> element without <eventTime>.
+.TP
+.BR "\-O \fIFILE\fP\fR,\fP \-\^\-operational=\fIFILE\fP]
+Optional parameter for '\fBrpc\fP' and '\fBnotif\fP' \fITYPE\fPs, the \fIFILE\fP contains running configuration datastore and
+state data referenced from the RPC/Notification. The same data apply to all input data \fIFILE\fPs. Note that the file
+is validated as '\fBdata\fP' \fITYPE\fP. Special value '\fB!\fP' can be used as \fIFILE\fP argument to ignore the external references.
+.TP
+.BR "\-y \fIYANGLIB_PATH\fP"
+Specify path to a yang-library data file (XML or JSON) describing the initial context.
+If provided, yanglint loads the modules according to the content of the yang-library data tree.
+Otherwise, an empty content with only the internal libyang modules is used. This does
+not limit user to load another modules explicitly specified as command line parameters.
+.
+.SH FORMATS
+There are two types of formats to use.
+.TP
+.I Schemas
+In case of schemas, the content can be converted into the '\fByang\fP', '\fByin\fP'
+and '\fBtree\fP' formats. As input, only YANG and YIN files are
+accepted. Note, that the corresponding file extension is required.
+.TP
+.I Data\ \ \
+In case of YANG modeled data, the content can be converted between '\fBxml\fP'
+and '\fBjson\fP' formats. Remember that the corresponding file extension of the
+input file is required.
+.
+
+.SH EXAMPLES
+.IP \[bu] 2
+Open interactive environment:
+    yanglint
+.IP \[bu]
+Convert YANG model into YIN and print it to the stdout:
+    yanglint --format=yin ./ietf-system.yang
+.IP \[bu]
+Convert ietf-system configuration data from XML to JSON:
+    yanglint --format=json --type=config --output=data.json ./ietf-system.yang ./data.xml
