# Rebase b2fe297..50178fe onto b2fe297
#
# Commands:
#  p, pick = use commit
#  r, reword = use commit, but edit the commit message
#  e, edit = use commit, but stop for amending
#  s, squash = use commit, but meld into previous commit
#  f, fixup = like "squash", but discard this commit's log message
#  x, exec = run command (the rest of the line) using shell
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
## END EDITOR WINDOW

## Current branch: (note that the 4g commits have different 
## hashes than on the origin/1_6_2 branch. This is what is meant by 'modifying history'.)
[f90c730...] ~/dev/pim$ git log -n 3 --oneline 
f90c730 Made a slight change to 4g disable code, and added some more debug statements
b32a8ec Worked on disabling 4g for modems, via c++ code
b2fe297 Fixed bug in pdptransmit that caused files > 4k to get corrupted as they were sent


## Simulate what the condition on everyone else's computer will be:
~/dev/pim$ git checkout 1_6_2


## Set the origin/1_6_2 branch to the f90c730 commit that's on top of 1_6_0
## f90c730 Made a slight change to 4g disable code, and added some more debug statements

## Good. git push doesn't let you modify history unless you force it to.

## Force it to modify the branch destructively.

## Show how the current checked-out local 1_6_2 branch is different than the origin/1_6_2 branch:
[1_6_2] ~/dev/pim$ git log -n 1 --oneline 
50178fe Made a slight change to 4g disable code, and added some more debug statements
[1_6_2] ~/dev/pim$ git log -n 1 --oneline  origin/1_6_2

## Point the local 1_6_2 branch at the origin/1_6_2 commit instead,
## and change any local files which would have changed in the process.
## (i.e. make the working copy act as if we'd just done a merge between two commits)
