process_file(filename)
takes templated file .xxx.src and produces .xxx file where .xxx
is .pyf .f90 or .f using the following template rules:
'<..>' denotes a template.
All function and subroutine blocks in a source file with names that
contain '<..>' will be replicated according to the rules in '<..>'.
The number of comma-separated words in '<..>' will determine the number of
replicates.
'<..>' may have two different forms, named and short. For example,
named:
<p=d,s,z,c> where anywhere inside a block '<p>' will be replaced with
'd', 's', 'z', and 'c' for each replicate of the block.
<_c> is already defined: <_c=s,d,c,z>
<_t> is already defined: <_t=real,double precision,complex,double complex>
short:
<s,d,c,z>, a short form of the named, useful when no <p> appears inside
a block.
In general, '<..>' contains a comma separated list of arbitrary
expressions. If these expression must contain a comma|leftarrow|rightarrow,
then prepend the comma|leftarrow|rightarrow with a backslash.
If an expression matches '\<index>' then it will be replaced
by <index>-th expression.
Note that all '<..>' forms in a block must have the same number of
comma-separated entries.
Predefined named template rules:
<prefix=s,d,c,z>
<ftype=real,double precision,complex,double complex>
<ftypereal=real,double precision,\0,\1>
<ctype=float,double,complex_float,complex_double>
<ctypereal=float,double,\0,\1>
