+"""save and restore file timestamps for files in the repository
+
+Some initial reasonings:
+
+- configuration: versioned file :file:`.hgtimestamps`
+
+  Mercurial ini-style with a `[patterns]` section
+
+      patterns for timestamped files: default: all files w/o leading ".hg"
+
+- file timestamps to be stored in a versioned file :file:`.hgtimestamps.db`
+
+  * no JSON because in JSON all strings are Unicode, in Mercurials
+    filenames are **not** Unicode
+
+  * parsed as *binary* file
+
+  * set of record separators: CR and/or LF (0x0d, 0x0a)
+
+  * field separator: SPACE (0x20)
+
+    if fields contain a space or ``#`` or ``@``: put them into ``@``;
+    eventually duplicate ``@`` characters within
+
+  * comment block at the begin: retained by the writer
+
+      lines starting with: ``#`` to CR and/or LF
+
+  * first non-comment line: :version: VERSION
+
+  * optional second non-comment line: :encoding: ENCODING
+
+  (This is roughly simalar to a Perforce checkpoint.)
+
+- Otherwise mostly modelled after TimestampMod
