+;; Session-handling variables and procedures.
+;;
+;; A "session" corresponds to one .ly file processed on a LilyPond
+;; command line. Every session gets to see a reasonably fresh state
+;; of LilyPond and should work independently from previous files.
+;;
+;; Session management relies on cooperation, namely the user not
+;; trying to change variables and data structures internal to
+;; LilyPond. It is not proof against in-place modification of data
+;; structures (as they are just reinitialized with the original
+;; identities), and it is not proof against tampering with internals.
+;;
+;; As a consequence, session management is not sufficient for
+;; separating multiple independent .ly files in "-dsafe" mode: you
+;; should give each its own LilyPond process when reliable separation
+;; is mandatory.
+;;
+;; For standard tasks and programming practices, multiple sessions in
+;; the same LilyPond job should work reasonably independently and
+;; without "bleed-over" while still loading and compiling the
+;; relevant .scm and .ly files only once.
