# Usage:
|
|
|
2ff057 |
# (1) If you don't want the module to depend on the exact compiler
|
|
|
2ff057 |
# version then use ocaml-find-requires.sh -c, but this is not something
|
|
|
2ff057 |
# you should do normally.
|
|
|
2ff057 |
#
|
|
|
2ff057 |
# (2) For any modules which you want to ignore, use '-i Modulename'.
