10     # The git eclass is written to fetch the software sources from
11     # git repositories like the subversion eclass.
12     #
13     #
14     # Description:
15     # If you use this eclass, the ${S} is ${WORKDIR}/${P}.
16     # It is necessary to define the EGIT_REPO_URI variable at least.

60     ## -- EGIT_REPO_URI: repository uri
61     #
62     # e.g. http://foo, git://bar
63     #
64     # supported protocols:

75     ## -- EGIT_PROJECT: project name of your ebuild
76     #
77     # git eclass will check out the git repository like:
78     #
79     # ${EGIT_STORE_DIR}/${EGIT_PROJECT}/${EGIT_REPO_URI##*/}
80     #
81     # so if you define EGIT_REPO_URI as http://git.collab.net/repo/git or
82     # http://git.collab.net/repo/git. and PN is subversion-git.
83     # it will check out like:
84     #
85     # ${EGIT_STORE_DIR}/subversion
86     #
87     # default: ${PN/-git}.
88     #

100     #
101     # git eclass can apply pathces in git_bootstrap().
102     # you can use regexp in this valiable like *.diff or *.patch or etc.
103     # NOTE: this patches will apply before eval EGIT_BOOTSTRAP.
104     #
105     # the process of applying the patch is:
106     # 1. just epatch it, if the patch exists in the path.
107     # 2. scan it under FILESDIR and epatch it, if the patch exists in FILESDIR.
108     # 3. die.

130     #
131     # git eclass will repack objects to save disk space. However this can take a
132     # long time with VERY big repositories. If this is your case set:
133     # EGIT_REPACK=false

136    
137     ## - EGIT_PRUNE:
138     #
139     # git eclass can prune the local clone. This is useful if upstream rewinds and
140     # rebases branches too often. If you don't want this to happen, set:
141     # EGIT_PRUNE=false
