-# Entries in this file define how editor maps #import(...) directives
-#
-# A key that ends with '\:' maps an entire scheme to a directory tree
-#    (All ':' characters in the key must be escaped)
-# For example, an entry in this file such as
-#    foo\: = /user/name/some/dir
-# will map the following imports
-#    #import('foo:bar')             --> /user/name/some/dir/bar/bar.dart
-#    #import('foo:blat.dart')       --> /user/name/some/dir/blat.dart
-#    #import('foo:buzz/blue.dart')  --> /user/name/some/dir/buzz/blue.dart
-#
-# A key that does not end with '\:' maps a single import to a single file
-# For example, an entry in this file such as
-#    green\:light = /user/name/some/dir/mylib.dart
-# will map only
-#    #import('green:light')         --> /user/name/some/dir/mylib.dart
-#
-# A specific mapping (does not end with '\:') takes precedence
-# For example, given
-#    foo\: = /user/name/some/dir
-#    foo\:bar = /user/name/another/dir/myfile.dart
-# will map
-#    #import('foo:bar')             --> /user/name/another/dir/myfile.dart
-#    #import('foo:blue')            --> /user/name/some/dir/blue/blue.dart
-#
-# Paths that are not absolute are considered to be relative to editor installation directory.
-# Leading and trailing whitespace around keys and values is ignored.
-# This file is read exactly once when editor is launched
