Example for a colourised logging output.

This example uses "blessings" to handle console escape sequences. ``blessings``

dependencies. And it's code-base is very clean and small.

The example extends the core logging formatter (logging.Formatter) and
colourises the complete line. This takes advantage of any upstream updates
related to logging. When writing this against Python 2.7, the parent code

Download SRA run files for given sample names

Have all sample names in samples, one per line and run:

for sample in $(cat samples); do
    IFS=$'\n'
    for line in $(./sra-runs.py $sample); do
        echo $sample $line >> runs

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs
