10     # The git eclass is written to fetch the software sources from
11     # git repositories like the subversion eclass.

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

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     #

109     # NOTE: this patches will apply before eval EGIT_BOOTSTRAP.
110     #
111     # the process of applying the patch is:
112     # 1. just epatch it, if the patch exists in the path.
113     # 2. scan it under FILESDIR and epatch it, if the patch exists in FILESDIR.
114     # 3. die.

123     # EGIT_TREE must be set after 'inherit git'.

138     #
139     # git eclass will repack objects to save disk space. However this can take a
140     # long time with VERY big repositories. If this is your case set:
141     # EGIT_REPACK=false

144    
145     ## - EGIT_PRUNE:
146     #
147     # git eclass can prune the local clone. This is useful if upstream rewinds and
148     # rebases branches too often. If you don't want this to happen, set:
