I have similar needs to understand complex code base such as 5-20gb of Android platform code, so I wrote an webapp/site for that: It lets you cross reference and document any language with gigabytes of code, e.g. Android platform code. Jelly bean ~9 gb of code. Try it out: http://www.srcmap.org/s/sl.htm/p=android-4.2.2_r1 http://www.srcmap.org/s/sl.htm/p=android-4.2.2_r1 Sample Documents created from that app are here: http://www.srcmap.org/p/1/4af293f91271/Android_Init_startup_process.html http://www.srcmap.org/p/1/4af293f91271/Android_Init_startup_... http://www.srcmap.org/p/1/80c16319d25e/Docker.html http://www.srcmap.org/p/1/80c16319d25e/Docker.html http://www.srcmap.org/p/6/4a88339ceef3/mtpd_source_code_study_in_aosp_4_2_2__init_rc__c__java_VPNProfile_interaction_tracing.html http://www.srcmap.org/p/6/4a88339ceef3/mtpd_source_code_stud... http://www.srcmap.org/p/1/212c9a285186/Google_IO_2014____schedule_APP_Wearable.html http://www.srcmap.org/p/1/212c9a285186/Google_IO_2014____sch... The ux is ok. A few gigabytes of code db running in a cheapest $5 instance of Digital Ocean. The app is very simple ~8 mb of standalone binary, no external dependency do any other app/db.
