+Section 4.4.10 - 4.4.12 document the file name length (local file header and
+central directory), extra field length (local file header and central
+directory) and the file comment (central directory only). For these fields the
+following *optional* restriction is specified:
+
+```
+The length of the file name, extra field, and comment
+fields respectively.  The combined length of any
+directory record and these three fields SHOULD NOT
+generally exceed 65,535 bytes.  If input came from standard
+input, the file name length is set to zero.
+```
+
+In practice this is not a check that should be strictly enforced, as ZIP
+implementations tend to completely ignore it. As an example, in Python it
+is very easy to create a file where these fields together are larger than
+65,535 bytes:
+
+import zipfile
+z = zipfile.ZipInfo(40000*'a')
+z.comment = 65535*b'b'
+contents = 10*b'c'
+bla = zipfile.ZipFile('long_file_name_comment.zip', mode='w')
+bla.writestr(z, contents)
+bla.close()
+
+This will create a file with a very long file name and comment (output edited
+for length, indicated by `[...]`):
+
+
+$ zipinfo -v long_file_name_comment.zip 
+Archive:  long_file_name_comment.zip
+There is no zipfile comment.

+-------------------------------
+
+  Zip archive file size:                    145643 (00000000000238EBh)
+  Actual end-cent-dir record offset:        145621 (00000000000238D5h)
+  Expected end-cent-dir record offset:      145621 (00000000000238D5h)
+  (based on the length of the central directory and its expected offset)
+
+  This zipfile constitutes the sole disk of a single-part archive; its
+  central directory contains 1 entry.
+  The central directory is 105581 (0000000000019C6Dh) bytes long,
+  and its (expected) offset in bytes from the beginning of the zipfile
+  is 40040 (0000000000009C68h).
