Introduction

ccollect is a backup utility written in the sh-scripting language.
`ccollect` is a backup utility written in the sh-scripting language.
It does not depend on a specific shell, only `/bin/sh` needs to be
bourne shell compatible (like 'dash', 'ksh', 'zsh', 'bash', ...).

Incompatibilities
~~~~~~~~~~~~~~~~~
Versions 0.5 and 0.6
^^^^^^^^^^^^^^^^^^^^^
.The format of `rsync_options` changed:
- Before 0.6 it was whitespace delimeted
- As of 0.6 it is newline seperated (so you can pass whitespaces to `rsync`)
You can update your configuration using `tools/config-pre-0.6-to-0.6.sub.sh`.
.The name of the backup directories changed:
- Before 0.6: "date +%Y-%m-%d-%H%M"
- As of 0.6: "date +%Y%m%d-%H%M" (better readable, date is closer together)
For the second change there is no updated needed, as XXXX- is always before
XXXXX (- comes before digit).
Versions 0.4 and 0.5
^^^^^^^^^^^^^^^^^^^^^
Not a real incompatibilty, but seems to fit in this section:
