Poseidon provides a slick dialog to assist with the importation of source code. Several options are available when importing this code:
General Tab
Descend directories recursively — Easily add all files below the selected directory
Skip CVS and SCCS directories — Ignore version control files
Confirm guessed accessor methods — A dialog appears to verify that methods are indeed accessor methods
Java Tab

Arrays are modelled — Select either as data types or with a multiplicity of 1..n
Create diagrams (slows down import) — Unchecking this box will speed up importation.
