+/* Public options. Some are compile-time only, some are run-time only, and some
+are both. Most of the compile-time options are saved with the compiled regex so
+that they can be inspected during studying (and therefore JIT compiling). Note
+that pcre_study() has its own set of options. Originally, all the options
+defined here used distinct bits. However, almost all the bits in a 32-bit word
+are now used, so in order to conserve them, option bits that were previously
+only recognized at matching time (i.e. by pcre_exec() or pcre_dfa_exec()) may
+also be used for compile-time options that affect only compiling and are not
+relevant for studying or JIT compiling.
+
+Some options for pcre_compile() change its behaviour but do not affect the
+behaviour of the execution functions. Other options are passed through to the
+execution functions and affect their behaviour, with or without affecting the
+behaviour of pcre_compile().
+
+Options that can be passed to pcre_compile() are tagged Cx below, with these
+variants:
+
+C1 Affects compile only
+C2 Does not affect compile; affects exec, dfa_exec
+C3 Affects compile, exec, dfa_exec
+C4 Affects compile, exec, dfa_exec, study
+C5 Affects compile, exec, study
+
+Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
+E and D, respectively. They take precedence over C3, C4, and C5 settings passed
+from pcre_compile(). Those that are compatible with JIT execution are flagged
+with J. */
