ORAC-DR is designed to include all its directories in a single location and not to care where that location is. All ORAC-DR software is located relative to the directory described by the ORAC_DIR environment variable.
The standard layout is as follows.
Executable programs. This includes oracdr, oracman and others. Note that none of the programs that form part of ORAC-DR are binary. The core ORAC-DR system will run anywhere the necessary Perl modules are available.
All the recipe files. Contains a directory for each instrument (using upper case) usually matching the value of the ORAC_INSTRUMENT environment variable.
All the primitive files. Contains a directory for each instrument (using upper case) usually matching the value of the ORAC_INSTRUMENT environment variable.
Basic introductory documentation for ORAC-DR.
Library files required by ORAC-DR. Contains a perl5 directory with all the Perl modules used by the system. The perl5 directory is the usual value for the ORAC_PERL5LIB environment variable.
Image files used by the system. Contains the start up images for the display tools (in NDF format).
Main documentation. Contains a directory per document. Currently contains all the Starlink User Notes.
Graphical user interface definitions. Only used by oracdisp.
