-[Description:]
-
-Using an angle style of zero means angle forces and energies are not
-computed, but the geometry of angle triplets is still accessible to
-other commands.
-
-As an example, the "compute angle/local"_compute_angle_local.html
-command can be used to compute the theta values for the list of
-triplets of angle atoms listed in the data file read by the
-"read_data"_read_data.html command.  If no angle style is defined,
-this command cannot be used.
-
-The optional {nocoeff} flag allows to read data files with AngleCoeff
-section for any angle style. Similarly, any angle_coeff commands
-will only be checked for the angle type number and the rest ignored.
-
-Note that the "angle_coeff"_angle_coeff.html command must be used for
-all angle types. If specified, there can be only one value, which is
-going to be used to assign an equilibrium angle, e.g. for use with
-"fix shake"_fix_shake.html.
