Change the size of the short hash representation -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Change the size of the short hash representation First note that this number doesn't really matter, as we always check for ambiguous short hash ids.

    13

    14

the file hg.1.txt is the input file, to generate the man page:

    15

    16

asciidoc.py -d manpage -b docbook hg.1.txt

    17

xmlto man hg.1.xml

    18

    19

to display:

    20

groff -mandoc -Tascii hg.1 | more

    22

    23

to create the html page (without stylesheets):

    24
