▁aud iting . ▁Build s ▁in ▁views ▁that ▁use ▁the ▁M V FS ▁can ▁monitor ▁and ▁record ▁file ▁I / O ▁operations ▁performed ▁during ▁the ▁build ▁process ▁and ▁associate ▁each ▁such ▁event ▁with ▁the ▁command ▁that ▁triggered ▁it . ▁This ▁allows ▁Clear Case ▁to ▁produce ▁a ▁bill - of - material s ▁which ▁it ▁calls ▁a ▁Configuration ▁Record ▁( CR ) ▁for ▁all ▁builds ▁and ▁enable ▁trace ability ▁for ▁either ▁software ▁configuration ▁management ▁purposes ▁or ▁as ▁part ▁of ▁a ▁larger ▁application ▁lif ecycle ▁management ▁process . ▁Build ▁aud iting ▁is ▁performed ▁with ▁command - line ▁tools ▁such ▁as ▁a ▁built - in ▁make ▁tools ▁( om ake , ▁clear make ) ▁or ▁by ▁using ▁the ▁clear aud it ▁command , ▁which ▁can ▁invoke ▁another ▁build ▁tool , ▁such ▁as ▁Unix ▁make ▁( 1 ). ▁ ▁The ▁Version ed ▁Object ▁Base ▁( V OB ) ▁that ▁stores ▁versions ▁of ▁file ▁elements ▁and ▁directory ▁elements ▁also ▁stores ▁derived ▁objects ▁and ▁metadata ▁associated ▁with ▁these ▁object ▁types . ▁ ▁The ▁bill - of - material s ▁artifact ▁produced ▁as ▁the ▁result ▁of ▁build ▁aud iting ▁is ▁known ▁as ▁the ▁Configuration ▁Record . ▁It ▁contains : ▁ ▁The ▁build ▁procedure : ▁The ▁method ▁( script , ▁make file , ▁and ▁so ▁on ) ▁that ▁invoked ▁the ▁build . ▁ ▁Input s : ▁All ▁files ▁( and ▁their ▁specific ▁versions ) ▁that ▁were ▁used ▁for ▁a ▁particular ▁build . ▁ ▁Output s : ▁All ▁derived ▁object ▁( DO ) ▁files ▁( and ▁any ▁dependent ▁DO s ) ▁produced
