Changeset 491 for pkpgcounter/trunk/pkpgpdls/plain.py

Timestamp:

Message:

Major code cleaning. Now clearer, although probably a bit slower since
a file can be opened several times.
Now universal line opening mode is only used when needed (PS, PDF and plain
text), and binary opening mode is used for the other formats.
This mean we will be able to remove mmap calls wherever possible, finally.
