NAME
       fsplit - split a multi-routine Fortran file into individual files

SYNOPSIS
       fsplit [ -e efile] ... [ file ]

DESCRIPTION
       Fsplit  takes  as input either a file or standard input containing For‐
       tran source code.  It attempts to split the input into separate routine
       files  of  the  form _n_a_m_e_._f_, where _n_a_m_e is the name of the program unit
       (e.g. function, subroutine, block  data  or  program).   The  name  for
       unnamed  block  data  subprograms has the form _b_l_k_d_t_a_N_N_N_._f where NNN is
       three digits and a file of this  name  does  not  already  exist.   For
       unnamed  main programs the name has the form _m_a_i_n_N_N_N_._f_.  If there is an
       error in classifying a program unit, or if _n_a_m_e_._f already  exists,  the
       program  unit will be put in a file of the form _z_z_z_N_N_N_._f where _z_z_z_N_N_N_._f
       does not already exist.

       Normally each subprogram unit is split into a separate file.  When  the
       _-_e  option  is used, only the specified subprogram units are split into
       separate files.  E.g.:
            fsplit -e readit -e doit prog.f
       will split readit and doit into separate files.

DIAGNOSTICS
       If names specified via the _-_e option are not  found,  a  diagnostic  is
       written to _s_t_a_n_d_a_r_d _e_r_r_o_r_.

BUGS
       _F_s_p_l_i_t  assumes  the subprogram name is on the first noncomment line of
       the subprogram unit.  Nonstandard source formats may confuse _f_s_p_l_i_t_.

       It is hard to use _-_e for unnamed main programs and block  data  subpro‐
       grams since you must predict the created file name.
