*equivalents* are strings that should compare equal in a `compare-windows`
session. You can define such strings in a **.qerc** file in the directory of
one of the files being compared. This helps ignoring known changes such as
type of function renaming... Here is an example to help compare files between
the `bellard/quickjs` and the `quickjs-ng/quickjs` repositories:
```
define_equivalent("JS_DupValue(ctx, ", "js_dup(");
define_equivalent("JSValue", "JSValueConst");
define_equivalent("JS_NewInt32(ctx, ", "js_int32(");
define_equivalent("JS_NewInt32(ctx,\n", "js_int32(");
define_equivalent("JS_NewUint32(ctx, ", "js_uint32(");
define_equivalent("JS_NewUint32(ctx,\n", "js_uint32(");
define_equivalent("JS_NewBool(ctx, ", "js_bool(");
define_equivalent("JS_NewFloat64(ctx, ", "js_float64(");
define_equivalent("JS_EXTERN ", "");
define_equivalent("JS_EXTERN JS", "JS");
define_equivalent("JS_EXTERN JS_", "JS_");
ignore_equivalent = 1;
```
