Ubuntu Live CD remastering tool
Python Makefile
Latest commit 9fba42b Sep 10, 2016 @clearkimura committed on GitHub Pre412 (#122)
* Fixed desktop entry

'Version=' refers to Version of Desktop Entry Specifications (see https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html), and not the version of Customizer itself. Note that "Entries that confirm with this version of the specification should use 1.0." Sorted most important fields according to example specification for clarity (Version, Type, Name).

* Fixed typo

In line 26, revised from 'does not exists' to 'does not exist'.

* Fixed typo

In line 24, revised from 'ISO does not exists' to 'ISO does not exist'.

* Fixed typo

In line 26, revised from 'Allwoing' to 'Allowing'.

* Fixed typo and lettercase

In line 55, revised 'does not exists' to 'does not exist'; Line 62 and 64, revised 'this mean that' to 'this means'; Line 211, revised 'Compressed Filesystem' to 'compressed filesystem' to match sentence style in following line 218 'filesystem size'.

* Fixed typo

In line 22, revised from 'avaialable' to 'available'.

* Fixed minor bug

The error messages were not being displayed; This fix is based on [this pull request on forked repo](kamilion@b2020fd) by wjwwood. In line 48, revised from u'' to u'{}' instead of proposed u'{0}' to standardize code style in old stable repo (Both have been tested working in 14.04 host system).

* Update Contributors

Added 'wjwwood' who found a bug that cause error messages not being displayed. No changes made to hardcoded list in GUI, because 'Contributors' file is the original and up to date listing.

* Update to version 4.1.2

* Update ChangeLog


As January 2016, Customizer has been forked and is now being maintained at https://github.com/kamilion/customizer. For more details, see issue #70. The existing repository is now considered as "old stable".

In late 2010, this project was registered on Sourceforge.net. Since November 2011, documentation is contributed. As December 2011, Customizer development has moved to GitHub and has been tested thoroughly on Ubuntu 10.04 (Lucid Lynx). One year later, as December 2012, Customizer stable release has hit 3.2.3.

Between late-2014 and early-2015, Customizer was rewritten in Python with the goal to support Ubuntu releases newer than 12.04 and making it more stable and robust.
