- * A signature file has a very simple fixed format: three lines
- * of "object <sha1>" + "type <typename>" + "tag <tagname>",
- * followed by some free-form signature that git itself doesn't
- * care about, but that can be verified with gpg or similar.
- *
- * The first three lines are guaranteed to be at least 63 bytes:
- * "object <sha1>\n" is 48 bytes, "type tag\n" at 9 bytes is the
- * shortest possible type-line, and "tag .\n" at 6 bytes is the
- * shortest single-character-tag line. 
- *
- * We also artificially limit the size of the full object to 8kB.
- * Just because I'm a lazy bastard, and if you can't fit a signature
- * in that size, you're doing something wrong.
