Commands are first read from tt(/etc/zshenv); this cannot be overridden.
If the tt(RCS) option is unset, no further files are read; changing this
option after this point has no effect on initialization files, but may
affect behaviour on logout.  Subsequent behaviour is also modified by the
option tt(GLOBAL_RCS).  If it is unset at any point during initialisation,
later files in the tt(/etc) directory will not be read.  It is also
possible for a file in tt($ZDOTDIR) to re-enable tt(GLOBAL_RCS). Both
tt(RCS) and tt(GLOBAL_RCS) are set by default.

Commands are then read from tt($ZDOTDIR/.zshenv).
pindex(LOGIN, use of)
If the shell is a login shell, commands
are read from tt(/etc/zprofile) and then tt($ZDOTDIR/.zprofile).
Then, if the shell is interactive,
commands are read from tt(/etc/zshrc) and then tt($ZDOTDIR/.zshrc).
Finally, if the shell is a login shell, tt(/etc/zlogin) and
tt($ZDOTDIR/.zlogin) are read.

When a login shell exits, the files tt($ZDOTDIR/.zlogout) and then
tt(/etc/zlogout) are read.  This happens with either an explicit exit
via the tt(exit) or tt(logout) commands, or an implict exit by reading
end-of-file from the terminal.  However, if the shell terminates due
to tt(exec)'ing another process, the logout files are not read.
These are also affected by the tt(RCS) and tt(GLOBAL_RCS) options.

If tt(ZDOTDIR) is unset, tt(HOME) is used instead.
Those files listed above as being in tt(/etc) may be in another
directory, depending on the installation.
