--- Implementation of the basename register.
---
--- The basename register is like the filename register ("%), but instead of
--- returning the whole filename, it will return just the basename with one
--- extension removed.
---
--- Useful for Java when needing to reference the class.
---
--- This register is assigned to the character '$'
+--- Basename Register: returns the current filename without path and extension.
+---
+--- This is similar to the "%" register (full filename), but returns only
+--- the basename with one extension removed. Useful, for example, when referencing
+--- Java class names based on the file name.
+---
+--- This register is read-only and assigned to the character '$'.
