_C_l_a_s_s "_V_e_r_s_i_o_n_s"

_D_e_s_c_r_i_p_t_i_o_n:

     A class to record version number information. This class is used
     to report versions; to add version informaton to your own class,
     use 'Versioned-class'.

_M_e_t_h_o_d_s:

     The following are defined; package developers may write additional
     methods.

     '_n_e_w("_V_e_r_s_i_o_n_s", ...)' Create a new 'Versions-class' instance,
          perhaps with named version elements (the contents of '...')
          added. Named elements of 'versions' are character strings
          that can be coerced using 'package_version', or
          'package_version' instances, 'Versions-class' objects.

     '_o_b_j_e_c_t["_i_d"]' Obtain version information '"id"' from 'object'.

     '_o_b_j_e_c_t["_i_d"] <- _v_a_l_u_e' Create or update version information
          '"id"' on instance 'object'.

     '_o_b_j_e_c_t[["_i_d"]]' Obtain version information '"id"' from 'object'.
          The result is a list of integers, corresponding to entries in
          the version string.

     '_o_b_j_e_c_t[["_i_d"]] <- _v_a_l_u_e' Create or update version information
          '"id"' on instance 'object'.

     '_o_b_j_e_c_t$_i_d' Obtain version information '"id"' from 'object'.The
          result is a list of integers, corresponding to entries in the
          version string.

     '_o_b_j_e_c_t$_i_d <- _v_a_l_u_e' Create or update version information '"id"'
          on instance 'object'.

     '_s_h_o_w(_o_b_j_e_c_t)' Display version information.

     '_u_p_d_a_t_e_O_b_j_e_c_t(_o_b_j_e_c_t)' Update 'object' to the current
          'Versions-class' representation. Note that this does _not_
          update another class that uses 'Versions-class' to track the
          class version.

     '_a_s(_o_b_j_e_c_t, "_c_h_a_r_a_c_t_e_r")' Convert 'object' to character
          representation, e.g., '1.0.0'

     '_o_b_j_e_c_t_1 < _o_b_j_e_c_t_2' Compare 'object1' and 'object2' using version
          class information. Symbols in addition to '<' are admissable;
          see '?Ops'
