`ftp` directories

The AIPS++ ftp directories contain compressed tar files for distribution of AIPS++ sources. These reside directly under the AIPS++ master's root directory which on the AIPS++ master host aips2.nrao.edu is also the home directory of the anonymous ftp account, ~ftp/pub. This allows the ftp directories, the master RCS repository, and the archive RCS repository to be accessible via anonymous ftp.

         +-- master ---+...
         +-- archive --+...
~ftp ----+
         |             +-- master ---
         +---- pub ----+--- code ----
                       +-- import ---

There are three main ftp directories. The plain-text AIPS++ sources required for an end-user installation are stored in pub/code. Separate gzip'd tar files are provided for each AIPS++ package (see §1.1.1) in keeping with the optional nature of package installations.

Third-party public-domain software required by AIPS++ is redistributed in pub/import. If necessary, utilities essential for AIPS++ are automatically fetched from here by configure (p) when AIPS++ is first installed.

The pub/master directory serves as a repository for the update files produced by the code distribution system (see exhale (p)). exhale also creates a tmp subdirectory within it for the duration of its operation.

It is intended that ftp directories will also be provided for patches and distribution of binary installations once AIPS++ gains a user base. At that time consortium sites will also act as distributors of AIPS++ for their local geographic region, but until then the ftp distribution files will only be available from aips2.nrao.edu.
