126 | ;;; Commentary: | |
127 | ;;; | |
128 | ;;; This module implements "G-expressions", or "gexps". Gexps are like | |
129 | ;;; S-expressions (sexps), with two differences: | |
130 | ;;; | |
131 | ;;; 1. References (un-quotations) to derivations or packages in a gexp are | |
667b2508 LC |
132 | ;;; replaced by the corresponding output file name; in addition, the |
133 | ;;; 'ungexp-native' unquote-like form allows code to explicitly refer to | |
134 | ;;; the native code of a given package, in case of cross-compilation; | |
21b679f6 LC |
135 | ;;; |
136 | ;;; 2. Gexps embed information about the derivations they refer to. | |
137 | ;;; | |
138 | ;;; Gexps make it easy to write to files Scheme code that refers to store | |
139 | ;;; items, or to write Scheme code to build derivations. | |
140 | ;;; | |
141 | ;;; Code: | |
142 | ||
