+// Package geth contains the simplified mobile APIs to go-ethereum.
+//
+// The scope of this package is *not* to allow writing a custom Ethereun client
+// with pieces plucked from go-ethereum, rather to allow writing native dapps on
+// mobile platforms. Keep this in mind when using or extending this package!
+//
+// API limitations
+//
+// Since gomobile cannot bridge arbitrary types between Go and Android/iOS, the
+// exposed APIs need to be manually wrapped into simplified types, with custom
+// constructors and getters/setters to ensure that they can be meaninfully used
+// from Java/ObjC too.
+//
+// With this in mind, please try to limit the scope of this package and only add
+// essentials without which mobile support cannot work, especially since manually
+// syncing the code will be unwieldy otherwise. In the long term we might consider
+// writing custom library generators, but those are out of scope now.
+//
+// Content wise each file in this package corresponds to an entire Go package
+// from the go-ethereum repository. Please adhere to this scoping to prevent this
+// package getting unmaintainable.
+//
+// Wrapping guidelines:
+//
+// Every type that is to be exposed should be wrapped into its own plain struct,
+// which internally contains a single field: the original go-ethereum version.
+// This is needed because gomobile cannot expose named types for now.
+//
+// Whenever a method argument or a return type is a custom struct, the pointer
+// variant should always be used as value types crossing over between language
+// boundaries might have strange behaviors.
+//
+// Slices of types should be converted into a single multiplicative type wrapping
+// a go slice with the methods `Size`, `Get` and `Set`. Further slice operations
+// should not be provided to limit the remote code complexity. Arrays should be
+// avoided as much as possible since they complicate bounds checking.
+//
+// Note, a panic *cannot* cross over language boundaries, instead will result in
+// an undebuggable SEGFAULT in the process. For error handling only ever use error
+// returns, which may be the only or the second return.
