+.SH "NAME"
+\fBer_B\fR \- Sample a random graph from the Erdos\-Renyi model B
+.
+.SH "SYNOPSIS"
+\fBer_B\fR \fIN\fR \fIp\fR [\fIfileout\fR]
+.
+.SH "DESCRIPTION"
+\fBer_B\fR samples a random graph from the Erdos\-Renyi model B, i\.e\. a graph with \fIN\fR nodes where each of the <N(N\-1)/2> edges is created independently with probability \fIp\fR\. 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
+\fIp\fR
+Edge probability\.
+.
+.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_B 1000 0\.006
+.
+.fi
+.
+.IP "" 0
+.
+.P
+samples an undirected random network with \fIN=1000\fR nodes where each possible edge is created with probability \fIp=0\.006\fR\. The output of the command \fBer_B\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_B 1000 0\.006 > er_B_1000_0\.006\.net
+.
+.fi
+.
+.IP "" 0
+.
+.P
+will save the resulting graph in the file er_B_1000_0\.006\.net\. Notice the usage of the symbol ">" to redirect the output of the program to a file\.
