+If an ID is shared between two or more input files, this program will
+try to rename each occurence except for the first one. This operation
+might have false positives (attributes/cdatas that are mistakenly
+identified to contain the ID-to-be-renamed) and false negatives
+(attributes/cdatas that actually contain the ID-to-be-renamed but this
+is missed by the module), and as such svg-spritemaker will warn if
+duplicate IDs are detected. You can suppress this warning by setting
+the C<SVG_SPRITEMAKER_NO_DUPLICATE_WARNINGS> environment variable to a
+true value.
