Proguard rules -keep vs -keepclassmembers vs -keepclasseswithmembers

Reading proguard rules

I found my self facing three terms that seemed to be very similar keep keepclassmembers keepclasswithmembers

I couldn't understand the difference between those three rules, Can someone explain the difference a bit better and maybe an example as well

1) keep - preserve classes

2) keepclassmembers - preserve class members such as fields & methods

3) keepclasseswithmembers - preserve classes if they satisfy certain conditions based on members

Examples

1) preserve all classes extending android.app.Activity

-keep public class * extends android.app.Activity

2) preserve all member ( static field ) named CREATOR on the condition if they are implementing android.os.Parcelable

-keepclassmembers class * implements android.os.Parcelable { 
static ** CREATOR; 
}

3) preserve all classes if they have constructor ( mentioned below as init ) with parameters( Context, AttributeSet ) or ( Context, AttributeSet , int ) . 

-keepclasseswithmembers class * { 
public <init>(android.content.Context, android.util.AttributeSet); 
} 

-keepclasseswithmembers class * { 
public <init>(android.content.Context, android.util.AttributeSet, int); 
}
