The text versions of catalogues obtained from the CDS are usually accompanied by a description file which documents their contents. This description file is usually called ReadMe and contains a description in a standard form. catcdsin interprets the contents of a CDS ReadMe file and uses them to construct a CURSA STL description file for the catalogue. catcdsin does not alter the catalogue data file itself: both the ReadMe file and the STL description file constructed from it refer to the same catalogue file.
CDS ReadMe files can (and often do) contain descriptions of more than one catalogue (usually these will be closely related catalogues or tables; perhaps a main catalogue and a table of notes). catcdsin creates a separate STL description file for every catalogue found in the ReadMe file.
The names of the catalogue files are included in the ReadMe file and STL description file names are constructed from them; the user cannot specify the description file names. However, there are several options which can be specified. By default catcdsin reads a file called ReadMe, though a different name can be given. By default catcdsin attempts to interpret columns of angles in the ReadMe file and construct valid STL angular column descriptions from them, though this behaviour can be suppressed. Optionally, parameters specifying the equinox and epoch of the coordinates can be added to the STL description files.
