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