+er_A(1) -- Sample a random graph from the Erdos-Renyi model A
+======
+
+## SYNOPSIS
+
+`er_A` <N> <K> [<fileout>]
+
+## DESCRIPTION
+
+`er_A` samples a random graph with <N> nodes and <K> 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 <fileout>
+is provided, the output is written on a file with that name.
+
+## PARAMETERS
+
+* <N>:
+    Number of nodes in the final graph.
+
+* <K>:
+    Number of edges in the final graph.
+
+* <fileout>:
+    The (optional) name of the filename where the edge list of the
+    graph will be saved.
+
+## EXAMPLES
+
+The following command:
+
+         $ er_A 1000 3000
+
+samples an undirected random network with <N=1000> nodes and <K=3000>
+edges using the Erdos-Renyi model A. The output of the command `er_A`
+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:
+
+          $ er_A 1000 3000 > er_A_1000_3000.net
+
+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.
