1mNAME0m\
        getdap4 - test driver for the libdap library DAP4 protocol

1mSYNOPSIS0m\
        1mgetdap4 \[dD vVikmzst\] \[-c 4m22mexpr24m 1m\] \[-m 4m22mnum24m 1m\] 4m22murl24m 1m...0m

       1mgetdap4 \[-VvksM\] 4m22mfile24m 1m...0m

1mDESCRIPTION0m\
        1mgetdap4  22mA  command  line  interface  for  DAP4, the follow-on to DAP2.\
        While getdap can be used to access DAP2 response  objects  and  process\
        those responses with the libdap client-side software, getdap4 fills the\
        same role for DAP4.

       In  the  first form of the command, dereference the URL and perform the\
        requested operations. This includes routing  the  returned  information\
        through  the  DAP  processing library (parsing the returned objects, et\
        c.). If neither of d or D are used with a URL,  then  the  DAP  library\
        routines are NOT used and the URLs contents are dumped to standard out-\
        put.

       In  the  second form of the command, assume the files are DAP4 Data ob-\
        jects (stored in files or read from pipes) and process them  as  if  -D\
        were given. In this case the information must contain valid MIME header\
        in order to be processed or -M should be used.

1mOPTIONS0m\
        \-i     For each URL, get the server version.

       \-d     For each URL, get the the DAP4 DMR response.

       \-D     For each URL, get the the DAP4 Data response.

       \-v     Verbose output.

       \-V     Version of this client; see 'i' for server version.

       \-c expr\
               4mexpr24m  is a constraint expression. Used with -D/X.  You can use a\
               \`?' for the CE also.

       \-k     Keep temporary files created by libdap.

       \-m num Request the same URL 4mnum24m times

       \-z     Ask the server to compress data.

       \-s     Print Sequences using numbered rows.

       \-M     Assume data read from a file has no MIME headers (the default is\
               to assume the headers are present).

1mFILES0m\
        4m~/.dodsrc0m\
               The 4m.dodsrc24m file contains various  parameters  that  affect  the\
               runtime behavior for DAP clients.  See 1mdodsrc22m(5) for further de-\
               tails.

1mENVIRONMENT0m\
        DODS\_CONF\
               Specifies an alternate file or directory for the 4m.dodsrc24m file.

1mDIAGNOSTICS0m\
        Various self-explanatory messages may be issued on stderr.

1mBUGS0m\
        The  command name should have been chosen more carefully to reflect its\
        purpose.

       The dodsrc man page needs to be written.
