Please find enclosed version 0.130 of the IBIS 5.1 draft (these copies, along with a Microsoft Word version, have been posted to the website). Note the following changes: - Bob Ross's new Section 10 structure has been implemented - Improved formatting on all figures - Corrections to keyword/required formatting - Single and double quote consistency - Grammatical fixes - Additional text in Section 1 on 5.1 features - Updated UI description text - Consistent use of format on "Example/Examples" - "Shall" for "must" in Section 6C and Section 10 Please check over Sections 6C and 10, particularly on the placement of Gaussian and related terms (new text is still needed there). Additionally, parts of Section 10 may still need reordering to make String, Float, Integer, etc. more global. - MM
