+
+.SH DESCRIPTION
+.PP
+\fBflatbeh\fP synthetize a VHDL behavioral data-flow description from a
+structural description. It flattens the structural description (it can be
+a hierarchy of macro block) until the cells which have a behavioral
+description. Then it raise all the equations and create a behavioral
+description of the root file.
+
+.SH PARAMETERS
+.PP
+\fBroot_structural_file\fP is the filename of the root of the structural
+description file.
+
+\fBoutput_file\fP is the destination filename for behavioural description.
+
+.SH ENVIRONMENT VARIABLES
+.TP 20
+\fIMBK_CATA_LIB\fP
+list of directories containing descriptions. 
+The default path is the current directory (see mbk(1)).
+.TP 20
+\fIMBK_CATAL_NAME\fP
+Indicates the file where the behavioral description files are given. This serves
+to flatbeh to stop the flatten of the structural root circuit.(see mbk(1))
+.TP 20
+\fIMBK_IN_LO\fP
+file extension for structural entity. (see mbk(1))
