+.SH "NAME"
+\fBer_A\fR \- Sample a random graph from the Erdos\-Renyi model A
+.
+.SH "SYNOPSIS"
+\fBer_A\fR \fIN\fR \fIK\fR [\fIfileout\fR]
+.
+.SH "DESCRIPTION"
+\fBer_A\fR samples a random graph with \fIN\fR nodes and \fIK\fR edges from the Erdos\-Renyi model A, i\.e\. the ensemble of random graphs where K links are placed uniformly at random among N nodes\. The program dumps the edge list of the resulting graph on output\. If the optional \fIfileout\fR is provided, the output is written on a file with that name\.
+.
+.SH "PARAMETERS"
+.
+.TP
+\fIN\fR
+Number of nodes in the final graph\.
+.
+.TP
+\fIK\fR
+Number of edges in the final graph\.
+.
+.TP
+\fIfileout\fR
+The (optional) name of the filename where the edge list of the graph will be saved\.
+.
+.SH "EXAMPLES"
+The following command:
+.
+.IP "" 4
+.
+.nf
+
+     $ er_A 1000 3000
+.
+.fi
+.
+.IP "" 0
+.
+.P
+samples an undirected random network with \fIN=1000\fR nodes and \fIK=3000\fR edges using the Erdos\-Renyi model A\. The output of the command \fBer_A\fR will be the edge\-list of the resulting graph, where each (undirected) edge is reported only once\. In order to be useful, such edge\-list should be saved into a file\. The following command:
+.
+.IP "" 4
+.
+.nf
+
+      $ er_A 1000 3000 > er_A_1000_3000\.net
+.
+.fi
+.
+.IP "" 0
+.
+.P
+will save the resulting graph in the file er_A_1000_3000\.net\. Notice the usage of the symbol ">" to redirect the output of the program to a file\.
