       DESCRIPTION

       The program uses a large set of environment variables to
       control its behavior.  These are initialized when the
       program is first started.  Several environment files are
       read to initialize variables specific to your site.  Many of
       these may be changed to suit your needs.  Others are
       dependent on either graphics hardware, file structures or
       digitizer type.  These must be changed with care.

       The current value of a variable may be printed with this
       command.  If a variable is not given, the entire environment
       is printed.

       When you first start the _E_c_h_o program it looks for a file
       named It must exist, and be readable, in one of th following
       directories.  Th directories are searchd in tis order: th
       current directory (.), your edirectory (~), /usr/lib/ec/var/ec/usr/local/ec Only
       th first occurance will be accessed.  n(!Z=\n(.k)&(\n(Np=0))
       .br

       n(;2-\n(:J Th .ecfilemay define several variables.  Variables
       specific to certain commands may be contained in additional
       files defined by tis file.  n(!Z=\n(.k)&(\n(Np=0)) .br

       n(;2-\n(:J Any variable not defined in thse files will
       default to a reasonable internal value.  Ti \f3getvar\f2
       command will give an error message.  Tis default value can
       only be determined by looking in th appendix of tis manual
       (defaults.).
