Directories

There are several major directory areas you should understand if you wish to program or write documentation for AIPS++. You may wish to refer to the AIPS++ System Manual for further details.

1. There are the master source directories, which contain the sources of code and documentation ^1.1. Since these are master sources, you cannot directly modify them, rather you must modify them by checking them into your personal (see below) directory, modify them, and then check them back.
2. You modify source (program or documentation) in your personal directories. These directories shadow the master directories. Because new directories are created or deleted on occasion, you will sometimes need to run the mktree program to reflect any directory additions or deletions in the master directories.
3. Processed documentation directories. Documentation which has been processed (normally by being turned into PostScript and HTML) are placed into common directory tree. During development of the documents you will be working in your personal directories.
4. Binary directories. These are where common (shared among all programmers) programs and libraries go. These are architecture dependent. During class and program development you will be working in your personal directories.

The exact location of these directories will depend on how your local system was set up, but will be of the following form:

master

/aips++/code

personal

 /aips++/code

processed documentation

/aips++/docs

binary

/aips++/sun4sol_gnu or whatever architecture(s) you have at your installation.

Sometimes instead of /aips++ your common directories will be under /aips2/aips++ or /u/aips++ or some other location. You will need to ask locally.

Similarly, your personal directory need not be directly under your home directory -- you may put it anywhere you have Unix "write" permission.

The directory location of a source file is often written as something like code/doc/reference/Coding.latex. If you are working on it in your personal directory you would prepend this path with  /aips++ and if you wanted to look at the master version you would prepend the path with /aips++ (or wherever your common installation is).
