| The following explains the syntax and semantics of Start States in lrlex.<br> | ||
| A working example can be found in the repository at [lrpar/examples/start_states](https://github.com/softdevteam/grmtools/tree/master/lrpar/examples/start_states) | ||

Minor comment: # is really only for the top-level comment in an MD file (so the file should probably start with the line # Start states) and then these comments should be ##.

| # Motivation | ||
|
|
||
| Start states are a feature from lex which can be used to add a bit of context sensitivity to lexical analysis. |

"which can be used for context sensitive lexing" maybe?

| Additionally the lexer has a stack of states, and matching rules perform actions which modify the stack. | ||
|
|
||
| # The INITIAL start state | ||
| By default unless specified otherwise all lex rules are members of the *INITIAL* start state. |

I wonder if this section should come earlier and be called something like "Differences from POSiX lex"?

I moved this one section higher, Which I believe does make sense because the section higher had start state operators in it, and the section renaming did seem appropriate too.

This all looks good, and worth merging now. Can you line wrap to the same length as the other md files (I think 100 chars) and force push? |
|
Will try and do so later today, as well as going through and running all the code snippets. |
|
Because I made some additional changes (changed the link format so it would fit on 100 char lines), I was hesitant to squash/force push. I tested all the complete examples containing e.g. those containing I am happy with this now, and feel like it's ready for a squash. |
|
LGTM! Please squash. |

Despite the fact that I am the terriblest writer, here is a rough draft for a chapter on start states.
I still need to test the code examples and stuff so marking as draft, but would appreciate any feedback.
