+ Uses a SQL query to iterate through table looking for rows with:
+
+ - GROBID status 200
+ - known SHA-1 (base32 format)
+ - known timestamp
+
+ Looks up release (by identifier) and file (by SHA-1). If no release exists,

+
+ If no file exists, create one from metadata (using both direct and wayback
+ URLs), link to release, and insert.
+
+ If file exists, optionally update it:
+
+ - if no release match, match to the release
+ - if new URL not included, add it (and wayback)
+
+ Config options:
+ - default URL rel
+ - crawl id (for editgroup metadata)
+ - identifier type

+ TODO:
