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.

61     #
62     # e.g. http://foo, git://bar

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}.

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.

113     ## -- EGIT_BRANCH:
114     #
115     # git eclass can fetch any branch in git_fetch().
116 robbat2 1.8 # If set, it must be before 'inherit git', otherwise both EGIT_BRANCH and
117     # EGIT_TREE must be set after 'inherit git'.

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

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