The layout.wrm file is a simple, optional configuration file for AceDB which resides in the wspec directory and allows the database curator or user to change the order and layout of the items appearing on the opening class menu window of xace.
In this respect, it supplants the -V and -H options of the options.wrm file and gives more flexibility to the layout of the window. The list of classes on the menu is no longer rigidly restricted to a pattern of three evenly spaced columns. Using layout.wrm, the classes on the menu can be displayed in any number of columns (if in columns at all) and spaced out using blank lines or extra whitespace to emphasise groupings of related classes. It also allows subclasses to be placed anywhere on the menu (whereas previously they were placed at the end of the list of classes).
Upon executing, xace simply replicates the pattern (including whitespace characters and blank lines) shown in layout.wrm character by character on the class window. For example, the following pattern in layout.wrm :-
Chromosome Clone Author
Gene Sequence Laboratory
Rearrangement Genome_Sequence Cell
Allele cDNA_Sequence Pathway
Strain Other_locus Sequence_map
Gene_class
Model Keyset
will produce the following window layout:-

Altering the above layout.wrm to remove some classes and change the ordering of the others as follows :-
Chromosome Clone Author Gene Sequence
Laboratory Rearrangement Genome_Sequence
Cell Sequence_map cDNA_Sequence
Pathway Allele Gene_class
Model Keyset
will alter the layout of the window to the following slightly less ordered schema :-
