# this module is an OS/2 oriented replacement for the grp standard
2+
# extension module.
3+
4+
# written by Andrew MacIntyre, April 2001.
5+
# released into the public domain "as is", with NO WARRANTY

# note that this implementation checks whether ":" or ";" as used as

"""Replacement for grp standard extension module, intended for use on
11+
OS/2 and similar systems which don't normally have an /etc/group file.
12+
13+
The standard Unix group database is an ASCII text file with 4 fields per
14+
record (line), separated by a colon:
15+
- group name (string)
16+
- group password (optional encrypted string)
17+
- group id (integer)
18+
- group members (comma delimited list of userids, with no spaces)
19+
20+
Note that members are only included in the group file for groups that
21+
aren't their primary groups.
22+
(see the section 8.2 of the Python Library Reference)
23+
24+
This implementation differs from the standard Unix implementation by
25+
allowing use of the platform's native path separator character - ';' on OS/2,
26+
DOS and MS-Windows - as the field separator in addition to the Unix
27+
standard ":".
28+
29+
The module looks for the group database at the following locations
30+
(in order first to last):
31+
- ${ETC_GROUP} (or %ETC_GROUP%)
32+
- ${ETC}/group (or %ETC%/group)
33+
- ${PYTHONHOME}/Etc/group (or %PYTHONHOME%/Etc/group)
