#!/usr/bin/env python
"""
Remembers or restores the original posting date of entry.
Filename may be given in commandline argument, if not so,
program asks for it.
If dealing with file first time, program reads the modified-time
and stores it as a tag:
#published %Y-%m-%d %H:%M:%S
e.g.
#published 2007-05-15 15:30:28
right after entry title line. The current modified-time of file is
preserved.
If run on the same file again and if the modified-time has been
changed since the time of tag storage, script restores the saved
time (sets it as the current modified-time).
That's all.
Program is rather pyblosxom utility than plugin, so there is no
reason to move it to plugins dir.
There are many ways how to use the script. I personally use CVS as
a primary storage for blog entries. But there is problem - CVS does
not honor mtime. So, I run the rdate.py once on files before adding
them to CVS. Then i update blog from the repository, but, we know,
cvs does it without correct mtimes. So, after blog update I run the
rdate.py on files once more to restore saved time from #published
tags. Simple bash scripts does this automatically for me, so I care
for blog entry times no more.
