_A_r_g_u_m_e_n_t_s:

      ac: A character vector of Accession number or NULL (default)

_D_e_t_a_i_l_s:

     If 'ac' is a vector of Accession number,  pfamAC2HOMSTRAD will
     return a list of associated HOMSTRAD ID for the given 'ac'.  If
     'ac' is NULL,  pfamAC2HOMSTRAD(ac=NULL) (or pfamAC2HOMSTRAD())
     will return a list of associated HOMSTRAD ID for all the Accession
     number in the database. Extra information:  None More Details:
     HOMSTRAD (HOMologous STRucture Alignment Database, \<URL:
     http://www-cryst.bioc.cam.ac.uk/homstrad/>) is a curated database
     of structure-based alignments for homologous protein families.
