The "data" directory is intended to hold data files that will be used by this module and will
2+
not end up in the .jar file, but will be present in the zip or tar file. Typically, data
3+
files are placed here rather than in the resources directory if the user may need to edit them.
4+
5+
An optional data/languages directory can exist for the purpose of containing various Sleigh language
6+
specification files and importer opinion files.
7+
8+
The data/build.xml is used for building the contents of the data/languages directory.
9+
10+
The skel language definition has been commented-out within the skel.ldefs file so that the
11+
skeleton language does not show-up within Ghidra.
12+
13+
See the Sleigh language documentation (docs/languages/sleigh.htm or sleigh.pdf) for details
14+
on Sleigh language specification syntax.
