+.SH NAME
+
+rnetclient \- Submit the Brazilian Income Tax Report to the Brazilian
+Tax Authority
+
+.SH SYNOPSIS
+.B rnetclient
+[\-d|\-\-declaration] <FILE> [\-o <DIRECTORY>|\-\-output-dir=<DIRECTORY>]
+.br
+
+.SH DESCRIPTION
+
+\fBrnetclient\fP is used to send Brazilian tax income reports to
+Receita Federal, Braziliam Tax Authority. It communicates with the
+official server from Receita Federal, ensures a secure connection is
+established, and submits the file. It is the product of
+reverse-engineering ReceitaNet, which is the proprietary, non-free
+version of the software that does the same thing as \fBrnetclient\fP.
+
+.SH OPTIONS
+
+.\" --declaration
+.TP
+.B \-d <FILE>, \-\-declaration=<FILE>
+Provide the declaration (report) filename to be sent to Receita
+Federal. This argument is mandatory. For historical reasons, the
+user can also provide the declaration filename without specifying the
+\fB\-d\fP modifier.
+
+.\" --output-dir
+.TP
+.B \-o <DIRECTORY>, \-\-output\-dir=<DIRECTORY>
+Specify the output directory where the receipt will be saved. This
+argument is optional; if no output directory is specified, then the
+receipt will be saved in the current working directory (CWD).
+
+.\" --version
+.TP
+.B \-V, \-\-version
+Print the program version and exit.
+
+
+.SH HISTORY AND MOTIVATION
+
+There is no way to talk about rnetclient without mentioning
+IRPF-Livre, which is an older project started and maintained by
+Alexandre Oliva. This project exists because Receita Federal, the
+Brazilian Tax Authority, does not release the source code for the
+software used to fill the Brazilian Tax Income Report. Alexandre
+still fights to make Receita Federal release this program as Free
+Software, but he also decided to produce and release a Free version of
+the program. However, there was still another closed source software
+needed to fully be able to do your duties with the Brazilian
+government: the program used to submit the report to Receita Federal.
+That is how rnetclient was born.
+
+The program began as a personal project from Thadeu Lima de Souza
+Cascardo. He had to reverse engineer the proprietary software in
+order to replicate the functionality, and made the first release on
+2013. In 2014, Alexandre Oliva and Sergio Durigan Junior joined
+efforts and helped in the release of the second version.
