16! Bugfix: replace 'user_spectra' with 'user_read_restart_data' in call of
17! message
18!
19! 274 2009-03-26 15:11:21Z heinze
20! Output of messages replaced by message handling routine.
21!
22! 220 2008-12-18 07:00:36Z raasch
23! reading mechanism revised (subdomain/total domain size can vary arbitrarily
24! between current and previous run),
25! former file user_interface.f90 split into one file per subroutine
26!
27! Description:
28! ------------
29! Reading restart data from file(s)
30! Subdomain index limits on file are given by nxl_on_file, etc.
31! Indices nxlc, etc. indicate the range of gridpoints to be mapped from the
32! subdomain on file (f) to the subdomain of the current PE (c). They have been
33! calculated in routine read_3d_binary.
