It's the right tool.
 

but from tests it seems to require that switches
precede arguments rather than allowing them to be specified after, so
that doesn't seem very good, either.

 
That's the usual convention, first come the options (with optional
arguments), then the non-option arguments. Here's a syntax example
 
  yagol [-s] [-w width] [-h height] [-g[ngen]] [-d density]
        [-i infile] [-o outfile] [-r random-seed] [-u rule]
        [-k|-t[sec]|-l|-f] [-p|-n|-c] [-a[gen]] [-m[rate]]

Please ignore that example (I forgot it's C code using 'getopt()'
from the GNU C library). The features differ in some ways.

For ksh's 'getopts' type in a ksh terminal 'getopts --man' to get a
more extensive manual information than that you find in 'man ksh'.
