_D_e_s_c_r_i_p_t_i_o_n:

     This is a wrapper function that calls all the necessary functions
     to detect missing annotation packages, ensure all versions are
     compatible with the current version of annaffy,and download
     required packages. This is an internal function and should not be
     called by the end user.

_U_s_a_g_e:

     chkPkgs(pkg)

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

     pkg: The chip-level annotation package

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

     This function checks for the correct chip-level package, and if it
     is not installed will download and install. In the case that there
     are two versions of the same package installed, the function will
     return the library location of the package with the correct
     version.

_V_a_l_u_e:

     This function doesn't return anything; it is only called for its
     side effect of loading or installing a chip-level annotation
     package.
