## Instructions for updating gnulib on development branch

## Change directory to the local Octave repositoy and clone the gnulib git
## repository:
git clone git://git.savannah.gnu.org/gnulib.git gnulib-git

## Convert to hg (might take some time):
hg --config extensions.convert= convert ./gnulib-git ./gnulib-hg

## Change directory to the gnulib sub-repo in Octave and execute the following
## commands:
cd ./gnulib
hg pull default
hg update
hg log -rtip --template "{node}\n"

## Take note of the SHA-1 hash (LAST_OLD_HASH) of that revision.

## Locate the first new revision in the converted repository and replace it in
## the following command:
cd ../gnulib-hg
hg log -r20111 --template "{node}\n"

## Take note of the SHA-1 hash (FIRST_NEW_HASH) of that revision.

## Change to the main directory of the local Octave repository and execute the
## following command replacing the hashes with the information just gathered:
cd ..
echo FIRST_NEW_HASH LAST_OLD_HASH > splicemap

## Execute the following command (having replaced FIRST_NEW_HASH):
hg --config extensions.convert= convert ./gnulib-hg ./gnulib --splicemap ./splicemap --config convert.hg.startrev=FIRST_NEW_HASH

## In the Octave repository do the following:
cd gnulib
hg update
cd ..
hg commit -m "maint: update gnulib subrepo."
hg push default -r .
